The Second Brain Map
This is what a second brain actually looks like. Below is a live map of a demo vault — eight weeks of daily yaps by Sam, 54, who started with four empty folders and one talking habit. Every dot is a note. Every line is a link Sam typed with two square brackets. This is exactly the graph view Obsidian draws of your vault, for free. Drag the dots. Click any note to read it. Press Grow to watch the eight weeks happen.
Teal pills are this note's [[wiki-links]] — click one to follow the thread, exactly like in Obsidian.
Notice the shape: the yaps (blue) feed everything, the master note sits in the middle like a sun, and no note is more than a couple of threads from any other. Nobody planned that layout — it grew out of one habit. Yours will too.

Doug teaches this live: everyone leaves with a working vault. This map is now part of the lesson.

A map needs stars. Yap one messy thought, get it mapped into piles, and you've got your first note to file.
