Hopefully, you’re not going to need a lot of self-discipline today, because there will be too much temptation for you to be able to follow any rules! Start this day off assuming that your plans are not going to be followed completely. Let yourself off the hook. As long as you have a flexible attitude, then you won’t spend the entire day feeling guilty that you aren’t doing what you’re supposed to be doing. If it’s a day full of whims, then so be it. That isn’t such a bad thing.
