I think willpower is a crock. I don't believe in this phenomenon. A lot of times people use the excuse "If only I had the willpower to do such and such" or "Ugh, I have no willpower to say no to bad food" Sometimes we even give willpower credit when we have successes. "I had the willpower to avoid chocolate this week" or "I had the willpower to stay on plan"
Who is in charge here???
Take credit for your strengths as well as your weaknesses. If you ate a pound of chocolate, it's not because you lacked something and it made you fail, it's because you chose not to stick to your plan. Same thing goes for having a good week. You didn't have a good week b/c you have this magic thing called willpower, you had a good week because you treated your body well.
Just food for thought... what do you think?
