An Amazing Way to Index Your (Paper) Notebook

As far as I can tell, there are three ways to organize your catch-all notebook you carry around with you:

1. Realize that you’re taking notes chronologically anyway, so just flip through by dated entry and hope you find what you are looking for.
2. Number your pages (or get a notebook with numbered pages) and then keep the first three pages clear for your running Table of Contents.
3. Use a tagging system, like you would in Evernote.

Yeah, I know. The last one didn’t seem possible to me either. But then I read this. (You’re welcome.)
