Second Brain

A second brain is a place to capture and organize ideas and information. Instead of using a structure of folders, everything connects together with links.

There are second brain links all over my website. They will guide you from idea to idea. You never know what you might find!

If you want to create your own second brain, you might want to look at Foam, Roam, or Obsidian.
