The bullet journal was created by Ryder Carroll. His system for a calendar and a way to capturing actions is an interesting one. Many of my clients have bits of paper that pile on their desks and as Carroll puts it " it gets out of control." Over time he created a system that worked for him called the Bullet Journal.
For those of us who gravitate to pen and paper, this way of gathering next actions is great. I tried the system and loved certain parts of it. The indexing in the front of my moleskin notebook worked superbly. I also loved the legends he created-a checkbox for action, an arrow to forward actions from a previous month. You can check out more note legends on the Wave Productivity Pinterest board.
