I don't think I really started seeing true success on this weight-loss journey until I figured out in my own head why I was doing it. You see, it's not enough to simply want to lose a few pounds, get a little fitter or live a little healthier. You need something that's going to push you, drive you, inspire you.
Have you thought it through yourself? Can you boil it down to one, two or a few note cards? If you have, if you can and if you want to, email your contribution to firstname.lastname@example.org (be sure to include a link to your blog if you want it included).
