I actually lost weight by not obsessing. When I crave something I eat it and then I eat healthily, and I don't go: "Oh, I can't eat." It means I don't want to eat too much because I'm letting myself be comfortable with it. It's really interesting. It has worked for me.
I'm not one of those people that has to look myself up every five seconds to see what people are saying. That's been really helpful. I mean, you get thousands of compliments, and then one person will say something negative - and that's all you'll remember, that one person.
