If you haven’t caught on to the bullet journal trend, uh, what are you waiting for? Maybe you have not yet heard of a bullet journal, or you’ve seen examples of them, you just aren’t exactly sure what they are. A bullet journal is, essentially, a planner, diary, tracker, and organizer all in one. It can be anything you want it to be, whether it’s full of to-do lists or doodles or habit tracking lists or calendars of reminders or all of those things.
