Bullet Journaling is a hot topic right now on the internet, but what is it really? In short, it just a paper note book that you ... well ... take notes in. It really a simple system. I have been using a the same (sort of) system for a number of years now. Being in the army, I get a note book and I jot down bullet notes for tasks that need to be done at work, notes for soldier issues that need to be taken care of, and generally anything work related.
