A 12-point list provides reasons to use a to-do list, such as improving prediction of future needs, exercising memory, preventing forgetting tasks, feeling more comfortable with a holistic view of tasks, setting clear priorities by seeing the big picture, establishing task order, reducing the need to remember through notifications, managing time efficiently, verifying completed tasks, feeling proud of accomplishments, and using the key of time management to succeed by focusing on high priority tasks. An iPhone app called "Personal check list" is recommended for keeping an organized to-do list with emotion tracking.
