My motivation is time. Right now I have some, but when I (hopefully) get accepted to and upper class education cohort at my college, I will be taking 18 hours of classes three days a week and student teaching during the other two. This filp-flops for senior year, and then I go straight into teaching and paying off my student loans
I want to establish good eating habits, and a healthy lifestyle NOW not only because I'm tiered of being fat, but also that it's a lot easier to maintain than loose when your under stress, and I'm afraid that if I don't fix my bad habits now, when serious stress comes I will crack under pressure and get even bigger than I already am. That is not going to happen.
