- Work: job, meetings, deadlines, clients, projects
|
| 68 |
-
- Health: exercise, medical, diet, mental health

-
- Important: meaningful, should be done
|
| 83 |
-
- Not Important: low real impact

- Quick: 5-10 mins, very low focus
|
| 87 |
-
- Easy: 10-20 mins, low focus
|
| 88 |
-
- Flow: deep concentration needed
|
| 89 |
-
- Personal: life admin, little goal impact

6. time_estimate (integer): Realistic minutes to complete.
