No next subject, no next exam, no next course. For the first time in my life, I could do whatever I wanted, go wherever I wanted. And all those possibilities, which should have felt like freedom, paralyzed me. Because suddenly that big question showed up:</p><p><em><strong>What do I do with my life now?</strong></em></p><p>Since then I&#8217;ve been fighting that question. Not in a dramatic way. I didn&#8217;t go to a monastery, I didn&#8217;t have a breakdown. But in cycles. Every six months, every two years, it comes back. A kind of melancholy that doesn&#8217;t take away my smile or my energy, but it&#8217;s there, underneath everything, like a low hum in the background. A feeling that something is missing. That life can&#8217;t just be this.</p><h3>The depressing books</h3><p>My friend Alberto used to call them that. &#8220;Your depressing books.&#8221;</p><p>He was right. Ever since I was a teenager, I&#8217;ve been drawn to authors who look the void in the face. Camus and his absurd. Life has no meaning, and you live it anyway. Dostoevsky with his characters who try to put themselves above suffering and end up destroyed. Kafka and his people trapped inside systems they can&#8217;t understand or control. Something huge is happening, you don&#8217;t control it, and nobody asked if you wanted to take part. Huxley and Orwell with their dystopias where the future has already arrived and nobody wants to live in it. Hermann Hesse and his endless spiritual search. And Kundera, of course. A book called <em>The Unbearable Lightness of Being</em>, how was I not going to read it?</p><p>But one of the ones that hit me hardest was Houellebecq. I read <em>The Elementary Particles</em> on the riverbank in Marburg, at the end of my Erasmus, in the last month of my studies, and for a while it was my favorite book.</p><p>The story of two half-brothers. Michel, a brilliant molecular biologist who can&#8217;t connect with another human being. Bruno, consumed by desire and loneliness, bouncing between failed relationships and empty hedonism. Two men with everything society promised, destroyed from the inside.</p><p>And then, the ending. Michel helps create a new species, genetically reproduced, no sex, no desire, no suffering. Humanity goes extinct and gets replaced by something more comfortable. Huxley&#8217;s nightmare turned into a novel. A civilization that solves every need and loses every reason to live. I read it right when my own life stopped being linear.</p><p>Alberto used to laugh at my reading choices. &#8220;Why don&#8217;t you read something more cheerful?&#8221; I didn&#8217;t have a clear answer. I was just drawn to them. Something in those books connected with something in me that I couldn&#8217;t name.</p><p>What I didn&#8217;t see back then is that those authors weren&#8217;t just describing the void. They were already pointing at the way out.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank" href="https://substackcdn.com/image/fetch/$s_!Futz!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!Futz!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 424w, https://substackcdn.com/image/fetch/$s_!Futz!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 848w, https://substackcdn.com/image/fetch/$s_!Futz!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 1272w, https://substackcdn.com/image/fetch/$s_!Futz!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!Futz!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png" width="1456" height="1686" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/bee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:1686,&quot;width&quot;:1456,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:4847447,&quot;alt&quot;:null,&quot;title&quot;:null,&quot;type&quot;:&quot;image/png&quot;,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:&quot;https://letters.os1.so/i/195848863?img=https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png&quot;,&quot;isProcessing&quot;:false,&quot;align&quot;:null,&quot;offset&quot;:false}" class="sizing-normal" alt="" srcset="https://substackcdn.com/image/fetch/$s_!Futz!,w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 424w, https://substackcdn.com/image/fetch/$s_!Futz!,w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 848w, https://substackcdn.com/image/fetch/$s_!Futz!,w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 1272w, https://substackcdn.com/image/fetch/$s_!Futz!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fbee4060d-f1f9-43d9-8b3b-e02d476d5648_1658x1920.png 1456w" sizes="100vw" loading="lazy"></picture><div class="image-link-expand"><div class="pencraft pc-display-flex pc-gap-8 pc-reset"><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container restack-image"><svg role="img" width="20" height="20" viewBox="0 0 20 20" fill="none" stroke-width="1.5" stroke="var(--color-fg-primary)" stroke-linecap="round" stroke-linejoin="round" xmlns="http://www.w3.org/2000/svg"><g><title></title><path d="M2.53001 7.81595C3.49179 4.73911 6.43281 2.5 9.91173 2.5C13.1684 2.5 15.9537 4.46214 17.0852 7.23684L17.6179 8.67647M17.6179 8.67647L18.5002 4.26471M17.6179 8.67647L13.6473 6.91176M17.4995 12.1841C16.5378 15.2609 13.5967 17.5 10.1178 17.5C6.86118 17.5 4.07589 15.5379 2.94432 12.7632L2.41165 11.3235M2.41165 11.3235L1.5293 15.7353M2.41165 11.3235L6.38224 13.0882"></path></g></svg></button><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container view-image"><svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-maximize2 lucide-maximize-2"><polyline points="15 3 21 3 21 9"></polyline><polyline points="9 21 3 21 3 15"></polyline><line x1="21" x2="14" y1="3" y2="10"></line><line x1="3" x2="10" y1="21" y2="14"></line></svg></button></div></div></div></a><figcaption class="image-caption"><em>Sisyphus, Titian (1548-49). Museo del Prado, Madrid.</em></figcaption></figure></div><p>Camus said it through Sisyphus. A man pushing a rock up a mountain to watch it roll back down, forever. In Dostoevsky it&#8217;s the opposite. His characters only get saved when they accept suffering and connect with another human being. Kafka is the nightmare of not even being allowed to do that. Systems you don&#8217;t understand, where you can&#8217;t fight for anything. And Houellebecq reached the end of the road. What&#8217;s left when the struggle is gone.</p><p>They were all pointing at the same thing. But in my early twenties, all I saw was the void. I couldn&#8217;t see the mountain hidden inside it. Camus was the most explicit, but his frame never fully convinced me. Absurdism, accepting that nothing has meaning and living in rebellion against that, sounds good in an essay. At three in the morning on one of those sleepless nights, it doesn&#8217;t hold you up. I needed something more concrete.</p><h3>The answer I didn&#8217;t expect</h3><p>I found it last year in the most unlikely place. A terrorist&#8217;s manifesto. A book Alberto recommended to me, by the way. The same Alberto who laughed at my depressing books.</p><p>Ted Kaczynski, also known as the Unabomber, wrote <em>Industrial Society and Its Future</em> in 1995. I&#8217;m not going to defend what he did. He mailed bombs for 17 years, killed three people, and injured 23 others. But his diagnosis of society is, maybe, the most lucid I&#8217;ve ever read.</p><p>Kaczynski described what he called the &#8220;power process.&#8221; Human beings need to struggle for real goals. Not abstract ones. Real ones. The kind your life depends on.</p><p>For hundreds of thousands of years, life was direct. You&#8217;re hungry, you go hunt. If you hunt, you eat. If you don&#8217;t hunt, you don&#8217;t eat. No middleman, no abstraction. Effort and reward connected by a single thread. Your survival. You build a shelter, you sleep dry. You defend your people, they survive. Every action has real, immediate consequences you can see and touch.</p><p>And that effort, that daily fight that was hard and sometimes dangerous, filled you up. Not because it was pleasant, but because the reward was in the hunting itself. In the act of hunting, not the outcome. The effort of finding food for your family was, in itself, what gave the day meaning.</p><p>Today. You open an app and in ten minutes there&#8217;s hot food at your door. You turn the heating on with a button. You buy clothes without getting off the couch. You don&#8217;t need to hunt, build, or protect anyone. Technology has solved survival. And with it, it has erased the original source of meaning.</p><p>What happens when you don&#8217;t have to fight for the basics anymore? You invent substitutes. Kaczynski called them &#8220;surrogate activities.&#8221; Corporate careers, hobbies, piling up money far beyond any real need, likes on social media. They never fully satisfy. The one piling up money always wants more. The one climbing the corporate ladder never gets there. That insatiability is the signal. If the activity actually filled you up, there would be a point where you stopped. But it never comes, because the goal was artificial from the start. Your life didn&#8217;t depend on it.</p><p>I read that and felt like someone had finally put words to what I&#8217;d been feeling for years. It wasn&#8217;t that I was missing anything material. It was that I had too much comfort and not enough mountain. Camus had been right about the mountain, but Kaczynski explained <em>why</em> we need it and <em>what happens</em> when it gets taken away.</p><p>But Kaczynski diagnosed in the abstract. He told you <em>what</em> was happening, not <em>how</em> or <em>where</em>. I was missing the mechanism running in the real world, inside the current system.</p><h3>The YouTube professor</h3><p>And then, a few months ago, I found Jiang Xueqin. The latest person who has spoken to me directly, the way Kaczynski spoke to me, the way the &#8220;depressing books&#8221; spoke to me before that. Every once in a while, someone shows up who puts words to what you feel but can&#8217;t name. Jiang is the most recent one.</p><p>Jiang grew up poor in Toronto, the son of a cook and a seamstress. He studied literature at Yale, worked as a journalist in China, and now teaches philosophy at a high school in Beijing. He started recording his classes for his students and uploading them to YouTube. History, geopolitics, how the systems that govern us actually work. Today he has more than a million subscribers.</p><p>His analysis of consumerism is what hooked me. In the eighties, under Reagan and Thatcher, society shifted from being centered on the worker to being centered on the consumer. The government stopped promising you a good job and started promising you low prices and product variety. A subtle change with enormous consequences. You compete for prestige, you take on debt, you individualize, you lose solidarity. You develop an &#8220;economic logic.&#8221; You see everything through capital. Why are you studying? To get a good job. Why? To make money. Why? To buy things and post them on social media.</p><p>And here&#8217;s the part that got me. Consumerism is, in his words, &#8220;the perfection of slavery.&#8221; If you&#8217;re a slave, you rebel. But if you don&#8217;t know you&#8217;re a slave, and you actually like your cage, if you choose your own slavery, you never rebel. The perfect system. Brave New World without the science fiction.</p><p>Kaczynski&#8217;s surrogate activities (climbing the corporate ladder, piling up money, piling up followers) are the mechanism Jiang describes. Kaczynski diagnosed the void. Jiang showed me the machine that produces it.</p><p>And Camus had been right from the start. He just didn&#8217;t have proof. Kaczynski supplied it from theory, Jiang from the data.</p><h3>Loneliness as a symptom</h3><p>And then there&#8217;s the thing nobody wants to look at. We&#8217;re alone.</p><p>Not alone like &#8220;I don&#8217;t have plans on Saturday.&#8221; Actually alone. Structurally alone. We live in the most connected society in history and the loneliest one. More depression, more anxiety, more mental health crises than ever, even though technology gives us more than ever.</p><p>For Jiang, this is the direct consequence. Consumerism atomizes. It turns you into an individual, tears you out of community, sets you to compete against everyone. Solidarity disappears because it&#8217;s inefficient. Relationships become transactional. And in the end you&#8217;re left alone with your screen, scrolling reels at two in the morning, buying things you don&#8217;t need, optimizing your LinkedIn profile, while something rots inside you.</p><p>And his laboratory is East Asia. Japan, South Korea, China, Taiwan. The societies that industrialized fastest are the ones showing the symptoms first. Aging, structural loneliness, birth rates in free fall. But the extreme case is South Korea. Consumerism, capitalism, and individualism taken to the limit. And the result is right there in the data. A fertility rate of 0.75, the lowest in the world. You need 2.1 for generational replacement. Best case scenario, South Korea will be gone by 2150.

Samantha doesn&#8217;t win Theodore over with her processing power. She wins him over because she listens, she understands, she accepts him without conditions. Everything a real human could give him, but that requires vulnerability, effort, the risk of rejection. AI gives you the connection without the cost. And the cost was what made it real.</p><p>The people who talk to ChatGPT like it&#8217;s a therapist. The teenagers who share more intimacy with a chatbot than with their friends. Not to mention porn, already a substitute, and now AI generates whatever you want. Everyone who prefers the comfort of an AI that always says the right thing over the friction of a human who sometimes doesn&#8217;t. They&#8217;re all Theodore. They choose the substitute because the original costs too much.</p><p>AI doesn&#8217;t solve loneliness. It perfects it. It gives you a substitute so good you stop looking for the real thing.</p><h3>The survivor</h3><p>And thinking about all this, another name came to me. Someone who had reached the same conclusion from the opposite side. Viktor Frankl, psychiatrist and Auschwitz survivor, wrote it in <em>Man&#8217;s Search for Meaning</em>. The prisoners who survived weren&#8217;t the strongest. They were the ones with a purpose. A book to write, a child to find again. &#8220;He who has a <em>why</em> to live can bear almost any <em>how</em>.&#8221;</p><p>Frankl writes that in the camps there was one moment that separated those who survived from those who didn&#8217;t. When a prisoner stopped looking toward the future. He stopped asking &#8220;when do I get out of here?&#8221; and started asking &#8220;what for?&#8221; The ones who lost the <em>what for</em> died within days. Not from hunger or illness. From emptiness. In the place with the least comfort in the world, the lack of purpose killed faster than the lack of food.</p><p>But Frankl went beyond purpose. He wrote something Kaczynski could have written. Human beings don&#8217;t need a state without tension. They need to struggle for a goal worth the effort, a task they chose freely. And the other side, the part nobody quotes: anyone who has every comfort in the world but no real struggle, sinks. I had read this years ago. I didn&#8217;t really understand it until now.</p><p>A concentration camp survivor. A terrorist. A YouTube professor. Three people with nothing in common, except the same answer:</p><p><em><strong>Human beings need to struggle for something real. Meaning is in the struggle, in the mountain itself, not in the summit. Take away the mountain and something fundamental breaks.</strong></em></p><h3>Flattening the mountain</h3><p>Every wave of technology has stripped away another layer of real effort. The industrial revolution took the physical. Consumerism filled the hole with surrogate activities. Social media atomized us. But AI is something else.</p><p>AI automates effort itself. Not the physical kind. The cognitive kind. Thinking, writing, solving, creating. What Frankl, Kaczynski, and Jiang say gives life its meaning. And it&#8217;s happening at a speed we can&#8217;t process. Our brains don&#8217;t understand exponential growth. The first steps are invisible and the last ones overwhelm you. If you want to see how far this goes, I lay it out with data in another article <em>[to be published soon]</em>. Will Smith eating spaghetti was a meme three years ago. Today AI-generated video is indistinguishable from reality. What looks exaggerated today will be obvious tomorrow.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://letters.os1.so/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading OS&#185;!

Generating an &#8220;artistic&#8221; image without ever touching a brush. Building an app without reading a line of code. The effort disappears, and with it, the meaning.</p><p>Huxley predicted this in 1932. <em>Brave New World</em> isn&#8217;t a world of surveillance and punishment like <em>1984</em>. It&#8217;s a world of total comfort. The citizens take soma, a drug that erases any discomfort. You feel sad, you take soma. You feel anxious, you take soma. You never have to face anything. The State doesn&#8217;t need to repress because nobody wants to rebel. Why would they, if they&#8217;re happy? There&#8217;s infinite entertainment, sex without commitment, consumption without limits. John the Savage, the only character who comes from outside the system, asks for the right to suffer, to grow old, to fail. The Controller doesn&#8217;t understand why anyone would choose suffering.</p><p>Pixar told the same story in 2008. In <em>WALL-E</em>, humanity lives on a spaceship where everything is automated. They&#8217;re obese, passive, glued to screens, unable to walk. A garbage robot has more curiosity and more life in him than any human on board. It was a kids&#8217; movie, and it was supposed to be over the top. But look around. The average adult spends seven hours a day in front of a screen. Kids who can&#8217;t be bored without an iPad.

I get paid to make the technology more capable, more autonomous, more &#8220;useful.&#8221; And I&#8217;m good at it.</p><p>I always thought I didn&#8217;t fall into the consumerist game. I don&#8217;t care about cars or material things. I don&#8217;t even have a personal Instagram. But I did fall into the status game Jiang describes. Personal branding. Subscribers. Talks. The Head of AI title. It&#8217;s another version of the same mechanism. Competing for prestige instead of for possessions.</p><p>I have a <em>Her</em> tattoo on my arm. My entire personal brand revolves around the movie that predicts what I build. And I&#8217;m writing this article with the help of <a href="https://letters.os1.so/p/i-open-sourced-my-brain">Claude Code, an AI that lives in my notes and connects my ideas</a>. An article about why AI is a problem.</p><p>And for years I was completely passive on politics and society. Too busy playing the status game to think about it. But if the solutions to everything I&#8217;m describing are political, then my passivity is another form of complicity.</p><h3>What can&#8217;t be automated</h3><p>And yet.</p><p>There are moments when none of what I&#8217;ve written matters. A dinner with friends where nobody is looking at their phone. Training until you can&#8217;t push anymore. The sea. Sitting on a park bench just to feel the sun on your face. Loving someone. Being loved. The cinema, two hours in the dark letting a story go right through you. Reading something that&#8217;s not going to make you more productive. A three-hour conversation that goes nowhere and shifts something in you.</p><p>Theodore chose Samantha because she was easier. But easy doesn&#8217;t fill you up. None of this produces anything, none of it scales, none of it can be optimized. It only exists if you&#8217;re there. Vulnerable, present, no filter.</p><p>Sisyphus pushes the rock knowing it&#8217;s going to fall. He pushes it anyway. &#8220;Il faut imaginer Sisyphe heureux.&#8221; <em>We must imagine Sisyphus happy.</em> Not because the rock stops falling. But because the meaning is in the act of pushing it.</p><p>I know Kaczynski might be right.<br>I know my mountain might be artificial.<br>I know the rock will fall again.<br>But I keep pushing it.</p>]]></content:encoded></item><item><title><![CDATA[I Open Sourced My Brain]]></title><description><![CDATA[Obsidian, Claude Code, and the system I open-sourced to stop losing ideas forever.]]></description><link>https://letters.os1.so/p/i-open-sourced-my-brain</link><guid isPermaLink="false">https://letters.os1.so/p/i-open-sourced-my-brain</guid><dc:creator><![CDATA[Jesús Copado]]></dc:creator><pubDate>Mon, 20 Apr 2026 14:23:06 GMT</pubDate><enclosure url="https://substackcdn.com/image/fetch/$s_!7CRP!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Ff5ce3460-275b-4c45-9e72-b555b09941d2_1280x720.png" length="0" type="image/jpeg"/><content:encoded><![CDATA[<p>Just kidding.

Black Mirror, S03E04.</em></p><p>We&#8217;re not in that timeline. Not yet. But I did the closest thing I could: I open-sourced the <em>system</em> I use to think. Not my consciousness, but the structure, the workflows, and the AI automation that turn my raw thoughts into something I can actually navigate. A <a href="https://github.com/jesuscopado/second-brain-template">template on GitHub</a> that anyone can clone and start using today.</p><p>It&#8217;s not San Junipero. But it&#8217;s the best I can offer you in February 2026. Ask me again in 6 months.</p><h2>Ideas are like fish</h2><p>David Lynch, the filmmaker behind Twin Peaks (one of my favorite shows ever), Mulholland Drive, and some of the most unforgettable images in cinema, described how ideas work: &#8220;An idea comes and you see it and you hear it and you know it. It comes like on a TV in your mind.&#8221;</p><p>And then it&#8217;s gone.</p><p>You know the feeling. You&#8217;re in the shower, half-asleep, walking somewhere, and something clicks. A connection you hadn&#8217;t seen before. A sentence that lands exactly right. The shape of something you&#8217;ve been trying to articulate for weeks. For a few seconds you hold it. Clear, vivid, whole.</p><p>Then your phone buzzes. Someone asks you a question. You think &#8220;I&#8217;ll remember this later.&#8221;</p><p>You won&#8217;t.</p><p>Lynch compared it to fishing. Ideas are out there by the millions, but you can&#8217;t force them. All you can do is lower the bait and wait. When one bites, you see every detail. And one idea attracts the next. &#8220;I like to think of it as in the other room the puzzle is all together, but they keep flipping in just one piece at a time.&#8221; The first piece pulls in the rest. But it works both ways. Lose that first piece and the whole chain breaks. You don&#8217;t just lose one thought. You lose everything it would have attracted. The loss is invisible because you never find out what you missed.</p><p>Lynch said he forgot three incredible ideas in his life. I&#8217;ve lost hundreds. Maybe thousands. Not because I&#8217;m careless, but because I had no way to catch them in time.</p><p>The single most important thing you can do for your thinking is also the simplest: <strong>write the idea down before it leaves</strong>. Not in the right place. Not with the right tags. Just write it down. Anywhere. Now. Everything else is secondary to that first act of capture.</p><div id="youtube2-Fxr-7O1Bfxg" class="youtube-wrap" data-attrs="{&quot;videoId&quot;:&quot;Fxr-7O1Bfxg&quot;,&quot;startTime&quot;:null,&quot;endTime&quot;:null}" data-component-name="Youtube2ToDOM"><div class="youtube-inner"><iframe src="https://www.youtube-nocookie.com/embed/Fxr-7O1Bfxg?rel=0&amp;autoplay=0&amp;showinfo=0&amp;enablejsapi=0" frameborder="0" loading="lazy" gesture="media" allow="autoplay; fullscreen" allowautoplay="true" allowfullscreen="true" width="728" height="409"></iframe></div></div><h2>The graveyard of note-taking apps</h2><p>I&#8217;ve tried everything. Notion, Evernote, Google Keep, and most recently, handwritten notebooks. Each one started the same way: enthusiasm, a week of careful organizing, then silence. Three months later, 300 notes I&#8217;d never read again and the quiet guilt of another abandoned system.</p><p>The pattern repeated because every tool asked the same impossible question upfront: <em><strong>where does this go?</strong></em></p><p>I don&#8217;t know where it goes. I just had an idea in the shower and I need to write it down before it vanishes. Asking me to choose between &#8220;Work,&#8221; &#8220;Personal,&#8221; and &#8220;Ideas&#8221; while I&#8217;m still dripping wet is a guaranteed way to kill the thought.</p><p>I spent years thinking I was bad at note-taking. I wasn&#8217;t. I was fine at capturing. Terrible at organizing. And every system punished me for it by demanding structure <em>before</em> I knew what I was thinking. You can&#8217;t organize knowledge you haven&#8217;t processed yet. It&#8217;s like creating a playlist before hearing the songs.</p><h2>Then Alberto showed me his brain</h2><p>My friend Alberto Manzano had built something different. He showed me <a href="https://albertomanzano.github.io/SecondBrain/">his second brain in Obsidian</a>: a web of interconnected ideas. No folder hierarchy. No color-coded tags. Just ideas linked to other ideas, like a personal Wikipedia.</p><p>The method behind it is called Zettelkasten. <strong>One idea per note. No topic folders.</strong> Structure emerges from connections, not categories. You write the idea, link it to related ideas, and move on. Over time, clusters form on their own. You discover what you think about by watching which notes attract the most connections.</p><p>I took Alberto&#8217;s principles, built my own rituals around them, and adapted the whole thing for AI. For the first time, a note-taking system got more useful over time, not less. I had a second brain.</p><h2>Why Obsidian</h2><p>After years of fighting my tools, Obsidian did something radical: it got out of the way. No onboarding wizard, no subscription, no cloud sync I didn&#8217;t ask for. Just a folder of <strong>plain text files that I own</strong>. If Obsidian disappears tomorrow, I keep everything. Try exporting from Notion sometime. I dare you.</p><p>It has a graph view that turns your notes into a visual map. Dots for ideas, lines for connections. Lynch&#8217;s puzzle pieces, visible on screen. The more you write, the more structure reveals itself. You start seeing clusters you didn&#8217;t plan, patterns you didn&#8217;t notice while writing.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank" href="https://substackcdn.com/image/fetch/$s_!TGNn!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!TGNn!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 424w, https://substackcdn.com/image/fetch/$s_!TGNn!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 848w, https://substackcdn.com/image/fetch/$s_!TGNn!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 1272w, https://substackcdn.com/image/fetch/$s_!TGNn!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!TGNn!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png" width="1198" height="1086" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:1086,&quot;width&quot;:1198,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:308439,&quot;alt&quot;:null,&quot;title&quot;:null,&quot;type&quot;:&quot;image/png&quot;,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:&quot;https://jesuscopado.substack.com/i/194005707?img=https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png&quot;,&quot;isProcessing&quot;:false,&quot;align&quot;:null,&quot;offset&quot;:false}" class="sizing-normal" alt="" srcset="https://substackcdn.com/image/fetch/$s_!TGNn!,w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 424w, https://substackcdn.com/image/fetch/$s_!TGNn!,w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 848w, https://substackcdn.com/image/fetch/$s_!TGNn!,w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 1272w, https://substackcdn.com/image/fetch/$s_!TGNn!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F88ed035d-a58f-4360-8050-5229d5bf5ee6_1198x1086.png 1456w" sizes="100vw" loading="lazy"></picture><div class="image-link-expand"><div class="pencraft pc-display-flex pc-gap-8 pc-reset"><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container restack-image"><svg role="img" width="20" height="20" viewBox="0 0 20 20" fill="none" stroke-width="1.5" stroke="var(--color-fg-primary)" stroke-linecap="round" stroke-linejoin="round" xmlns="http://www.w3.org/2000/svg"><g><title></title><path d="M2.53001 7.81595C3.49179 4.73911 6.43281 2.5 9.91173 2.5C13.1684 2.5 15.9537 4.46214 17.0852 7.23684L17.6179 8.67647M17.6179 8.67647L18.5002 4.26471M17.6179 8.67647L13.6473 6.91176M17.4995 12.1841C16.5378 15.2609 13.5967 17.5 10.1178 17.5C6.86118 17.5 4.07589 15.5379 2.94432 12.7632L2.41165 11.3235M2.41165 11.3235L1.5293 15.7353M2.41165 11.3235L6.38224 13.0882"></path></g></svg></button><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container view-image"><svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-maximize2 lucide-maximize-2"><polyline points="15 3 21 3 21 9"></polyline><polyline points="9 21 3 21 3 15"></polyline><line x1="21" x2="14" y1="3" y2="10"></line><line x1="3" x2="10" y1="21" y2="14"></line></svg></button></div></div></div></a><figcaption class="image-caption"><em>My notes after one month. Each dot is a note, each line a connection.</em></figcaption></figure></div><p>There&#8217;s also a plugin ecosystem that makes it feel like more than a text editor. Excalidraw lets you draw diagrams right inside your notes, and even those are stored as plain text. Dataview lets you query your notes like a database. But you don&#8217;t need any of that to start. The core is just you, a folder, and your ideas.</p><h2>The part where AI walks in</h2><p>Here&#8217;s where it gets interesting. And honestly, a little uncomfortable.</p><p>I use Claude Code as my thinking partner. Not to think for me. To handle everything I was already failing to do by hand.</p><p>When I have a raw idea, I just dump it. Could be something from a YouTube video, a person I met, three disconnected thoughts from a walk. I don&#8217;t decide where it goes. Claude reads it, figures out what it is, checks if I&#8217;ve already captured something similar, and files it in the right place with links to related notes. The organizing happens without me. That&#8217;s the core of it. The thing Lynch was describing. You catch the fragment, and the system makes sure it connects to the rest.</p><p>From there it spread to everything. My projects, my calendar, my goals. I didn&#8217;t plan it. My notes just became the place where I do my thinking.</p><h2>The uncomfortable part</h2><p>There&#8217;s a tension in using AI to manage your thinking. When Claude suggests a connection between two notes, is that my insight or its pattern matching? When it surfaces a theme in my weekly review, did I discover it or did the machine? If I turned it all off tomorrow, could I still think the way I think now?</p><p>I don&#8217;t have a clean answer. I chose to automate the parts I was already failing at. I wasn&#8217;t manually connecting notes. I wasn&#8217;t doing weekly reviews. I wasn&#8217;t processing my inbox. Those things weren&#8217;t happening. The choice wasn&#8217;t between &#8220;manual effort&#8221; and &#8220;AI automation.&#8221; It was between nothing and something. <strong>I chose something.</strong></p><h2>Clone my brain</h2><p>I published the whole thing as a <a href="https://github.com/jesuscopado/second-brain-template">template on GitHub</a>. Clone it, open in Obsidian, run the onboarding, start using it. The skills, the folder structure, the plugins, all pre-configured.</p><p>The hardest part of any knowledge system isn&#8217;t the philosophy. It&#8217;s the setup. If I can remove that barrier, maybe more people will experience what Lynch was talking about. You write one idea down. It connects to another. That connection sparks a third you never expected. The system doesn&#8217;t just store your thinking. It generates more of it.</p><p>Over time, your notes become a mirror. It shows you what you actually care about, not what you think you care about. The clusters that form, the notes that attract the most links, the patterns that surface when you review your week. That&#8217;s your real map.</p><p>Most people think note-taking is about remembering. It&#8217;s not. <strong>It&#8217;s about thinking.</strong> This system works for me. Not because it&#8217;s perfect, but because it removed every excuse I had for not using it.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://letters.os1.so/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading OS&#185;!
