I have one which is half way between a catch all and a common place book. I intend to transfer it to my common placebook when I've made a dent. I'm around 20 pages into a 70 (?) page book. Not all pages are fully filled but I have some good notes to transfer and some other pages that were only used for active recall exercises. :D

I had a bullet journal but stepped away from that process now. I'm thinking of possibly turning that into my common place book, if not I'll use another notebook but it's nice to see other people have books to catch quick ideas rather than lugging around larger ones haha. :D
