Bullet Journaling is a customizable organization system that combines elements of a planner, diary, and to-do list. It uses simple symbols, like dots for tasks and circles for events, to help users track their daily activities, goals, and thoughts. This method encourages mindfulness and reflection, making it easier to manage time and priorities. The system was created by Ryder Carroll, a designer who aimed to simplify personal organization. Users can adapt their journals to fit their needs, incorporating sections for habit tracking, gratitude, and future planning. This flexibility makes Bullet Journaling popular among people seeking a creative outlet for productivity.
