The Bullet Journaling Method, created by Ryder Carroll, is a useful analog system in which you gather and organize everything from your grocery lists to your long-term goals and projects. It may serve as your daily, monthly, and yearly planner, personal journal, to-do list, travel log, and/or habit tracker. You can gather your off the wall ideas, write down useful information, and keep track of your appointments and assignments all in one book! Wow.
 
Your bullet journal becomes whatever YOU need it to be. You can keep it incredibly clean and simple, or creatively dress it up to the max.
