J.B.
I have never heard of this so I had to look it up. Sounds like something that's not really worth worrying about, give it a try! Pick up a journal at Staples or CVS or wherever, give it a go and if it's not for you, you're out a few bucks.
I use a Passion Planner, which I really like. It has some of the same ideas as the bullet journal (planning but also goal setting and sort of a diary) but you don't have to create the pages. There are lots of blank pages in the back for more creative layouts. I do like the index feature of the bullet journal and may work that into my Passion Planner's blank pages section.
