What's a bullet journal? A creative method of journaling and note—taking that uses bullet points as its core structure. The idea behind it is that you jot down quick notes instead of writing long sentences. Its owner logs anything they want, which can include symbols, charts, illustrations—often with a variety of colors provided pens and markers of the writer's choice—on a dotted grid background. Common uses are to chronicle daily activities, track habits, log appointments, keep calendars, plan trips, record random thoughts, and keep track of a diet.
