Stop setting up Obsidian until you can answer this one question about how your brain actually works

Before you spend a Saturday building a vault, picking a theme, and bookmarking 14 plugin tutorials, you need to sit with one question: Does your brain naturally connect ideas across topics, or does it prefer to sort them into clean categories? I've watched smart people bounce off Obsidian within their first month because they skipped that question. The app didn't fail them — they picked a tool that wasn't built to suit their brain.
