1. Keep track of the things you do

2. Plan ahead (appointments, birthdays, etc.)

3. Easy place to take notes

4. Log the activities that are important to you (exercise, sleep, what you ate)

5. Allows you to recollect past days

6. Helps you to break down big goals

7. Supports monthly, quarterly and annual reviews

8. Helps you identify what value-add activities you did (and what drained you)

9. Doesn't require any fancy software or apps

10. Helps your memory (because the act of writing is another way of engaging your senses)
