Firstly, you may be wondering just what a “bullet journal” might be. The concept’s developer, Ryder Carroll, has an excellent intro to the system here. Basically, a bullet journal (BuJo) is a freeform notebook/ task list/ daily to do list and much more.
I followed the BuJo system religiously for almost a year, trying to put my entire life into a bullet journal. It stopped working for me. I found it too distracting to have my day job, my personal stuff, and my novels, all in the same Leuchtturm A5 hardcover notebook. After racing through notebooks alarmingly quickly — when I got to two notebooks a month, I gave up. In the time I was copying Collections to new notebooks, I could have written a new chapter.
