Building a Second Brain

Remember that non-fiction doesn't require you to read cover to cover like fiction.

With that in mind, about 60% of this book is cool, and most of it is ignored by the people online making content about this topic. The primary advice discarded by these internet individuals is that the Second Brain is a habit, not one specific app. If you're going to build a Second Brain, design it as a system. It should branch multiple apps. It's a structure, not one app.
