There is a version of learning where you read a book, close it, and believe you now know the thing. I have tried that version many times. It doesn't take.
The version that works for me is building. Not the grand, well-scoped project with a roadmap — the scrappy, half-embarrassing one that I ship on a weekend because I wanted to see if it could exist.
Every project on this site started that way. A meal tracker because I was tired of typing into Notes. A CDK-powered personal website because static hosting was too simple and I wanted the excuse. A tool to watch my Strava data because I got competitive with myself.
If there is a thesis, it's this: the act of building forces a level of specificity that reading never will. You cannot hand-wave a schema. You cannot skim a race condition. You either made the thing work or you didn't.
That's why I keep building. Not because every project is important, but because the habit is.
