I'm going to describe something that might sound familiar. You heard about Building a Second Brain — maybe from Tiago Forte's book, maybe from a YouTube video, maybe from that one friend who won't stop talking about their Obsidian vault. You got excited. You set up Notion with a PARA system. You created databases for projects, areas, resources, and archives. You installed six browser extensions for clipping articles.
And then you spent the next three months organizing notes instead of writing anything.
Welcome to second brain fatigue. You're not alone.
The Numbers Tell the Story
Notion now has over 100 million users and hit $400 million in revenue in 2024. Obsidian holds about 8% of the note-taking market and dominates among power users. Roam Research, which was valued at $200 million in its seed round during the 2020 hype cycle, has seen its web traffic drop to around 1 million monthly visits while Obsidian grew to 5 million.
Here's the part nobody talks about: the tools are growing, but the output isn't. Users report that their knowledge bases became — and I'm quoting a Roam refugee here — "garbage dumps full of crufty links." Multiple analyses have started describing the entire PKM category as "productivity theater" — tools that look like they're helping but are actually time sinks.
Even Tiago Forte himself has acknowledged the problem. He's admitted that PKM is perceived as "highly technical and complex, like engineering" and that he "probably contributes to this perception more than anyone." When the person who popularized the framework says complexity is a problem, maybe it's time to listen.
The Capture Trap
The fundamental issue with most second brain setups is that they optimize for capture, not creation. You get really good at saving interesting articles, highlighting key passages, and filing things into the right folder. You feel productive because your note count keeps going up.
But there's a crucial difference between collecting ideas and developing them. A note you clipped from an article and tagged with three categories isn't knowledge — it's a bookmark with extra steps. Knowledge is what happens when you take that idea, wrestle with it in your own words, and connect it to something you've experienced.
That process has a name. It's called writing.
What the Consistent Publishers Actually Do
I've been paying attention to the people in my circle who actually publish regularly — not just capture notes, but put finished thoughts out into the world. They share a few traits.
First, they use embarrassingly simple tools. One friend writes everything in Apple Notes. Another uses a single Google Doc per month — just a running log of thoughts, and when one section gets long enough to be interesting, she publishes it. A developer I know keeps a plain text file called "drafts.md" and that's his entire content system.
Second, they minimize the gap between writing and publishing. A few of them use Cloudpad , which turns a Google Doc directly into a live website. One told me she switched to it specifically because she was "tired of her Notion wiki being a graveyard of almost-posts." She publishes three times a week now.
Third, they treat notes as disposable and posts as permanent. Instead of building an elaborate archive of captured snippets, they use notes as kindling — quick, messy, temporary — and the blog post is the real artifact.
The One-Tool Rule
Here's my challenge to anyone drowning in their second brain setup: try the one-tool rule for thirty days. Pick a single writing tool — ideally one you already have open — and do everything there. Capture ideas there. Draft posts there. Publish from there.
No syncing between apps. No tagging taxonomy. No weekly reviews of your knowledge graph. Just writing.
I know this sounds reductive. It is. That's the point. A simple Apple Notes setup used consistently will always beat an elaborate Obsidian vault abandoned after a month. The tool that produces output wins. Everything else is decoration.
