Even if you could make it through your to-do list in a given day, this is not a competition. There is no prize for completing your to-do list. And, even if you successfully crossed off every numbered item on your list in a given day, you will be met with another list the very next morning. The thing is, not everything on your to-do list should be done.
The colorful calendar is my guide to setting limits. No, I can't do that task because I already have too much yellow or orange on the calendar. It forces me to block off time for myself, my friendships and my family. If the section is blocked off with mint green (my time), I simply can't put something orange or purple there.
