Put it this way my friend. Do you know why those people always have a set of photos before and after weight loss? That's because they did commited in the first place, took the before photo. Once they have the before photo, they have no turning back, and the only way to go is, success. I don't know if this make sense for you, and this is also why I upload my workout video, because now everybody knows I'm commited, I can't back myself out anymore!
