I'm actually pretty good about going to the gym, but I'm overweight anyway. The reason is that I'm good at doing what I should do, but bad about not doing what I shouldn't do. A hard workout takes a while, but then you're done, and you feel great. Not eating the donut takes a while, but an hour later, you aren't done not eating the donut. Oh no, not at all. It still beckons.
