Prevention is the best medicine, and so is planning for your temptations. If you’re always hungry at three PM, pack a healthy lunch instead of grabbing your spare cash and getting a chocolate bar from a vending machine. If you want to stop arguing with other people and know a person who always drives you crazy, come up with a plan to avoid this person. When you plan for situations that can challenge your self-discipline too much, you reduce the risk of giving in to a temptation. Consequently, you prevent cravings instead of fighting against them.
