Bullet Journal

Bullet Journaling, also called “BuJo” is a popular system for organizing to-do lists, thoughts, schedules, and other activities. The name derives from the practice of using bullet points and abbreviated text to organize information. Users customize their journals, organizing content in ways to suit their needs.
While the type of content varies by creator, the organization of a bullet journal usually contains the same elements:
Index: a table of contents
Rapid logging: the symbols- bullets and dashes- used to simplify and organize information
Logs: to do lists, organized by day, week, month, or other unit of time
Collections: organization of content by type, such as an activity tracker or long term projects
Migration: the activity of updating lists and logs into new formats
