We often forget conditions change. It’s easy to swear off fatty foods right after we overeat and experience the discomfort of that decision. The conditions change when the discomfort of hunger drives us to crave that same meal that was so aversive when I was full only a few nights previous. If my commitments change as often as my conditions and circumstances, I am destined to be ruled by my stomach or feelings. It’s not until we draw a line in the sand and stick to a disciplined commitment that we can say we are making progress.
