People from my past.
Be it friends I've lost touch with, enemies(!), exes, people I really liked but never really struck up a friendship with or people I really DIDN'T like, I always think, "If I should bump into one of them tomorrow... Would I be happy with the way that I look now?" At the moment the answer is no, but it really motivates me to lose this excess weight so that hopefully one day I'll bump into somebody from my past and I'll be a really healthy-looking size 10 and look amazing. I don't know why this will bring me satisfaction, but I know that it will. On that note, I'm off to get an early night before my 4 mile power walk followed by C25K run tomorrow morning.
