I just wanted to say that so far, this is really, really working for me. I'm not entirely sure what is says about me that money is such a strong motivator for me, but i'll take it! Not only am I being motivated, but I feel like i'm creating and sticking to new healthy eating and activity habits. I plan to stick with this site for the long haul of reacing my goal.
Wish me luck, and good luck to you all!
