Using software to create a “second brain” is a concept I only stumbled across a few months ago, although I have, in essence, been doing the same thing for years. Our brains are skilled at coming up with new ideas, but we have a finite amount of storage to work with. Sure, you might still remember your high school locker code, but it isn’t always easy to shove more information into a space. That’s where a “second brain” comes in — a way to keep notes that allow us to more easily access learned knowledge and create links between ideas.
