I look at this two ways:
- Each day is a new day and you can start over with a clean slate.
- No matter what already happened today, you can still start over from this moment forward. After all, a day is 24 hours. You can restart your 24 hour stop watch at any point. I like this thought process because often when I mess up, I give up. For example, if I eat something I wasn’t planning to eat, I say, “screw it!” and binge.
