Interesting! I used a planner all throughout high school and later in college but fell out of the habit after undergrad. Since becoming a teacher I've struggled to keep one consistently as I used to when I was younger. I've adopted some of the bullet journal methods but haven't really migrated yet from planner books. I bought one last year that I bought because it was pretty but I'm really struggling to use it consistently. I finally made the connection a few weeks ago that it's because it's too big so using it becomes a chore since I need to have a clear desk.
