What does take real power is restraint — to not do things — especially when we want to do them. Fasting is restraint in action. I do feel hungry, I am confronted with tempting treats and tantalizing entrees. If I can learn to bypass them, I can learn to bypass a lot of tantalizing things, that in the long run, add little value.
