Trying to be perfect will only make you miserable. It's easy to become obsessed with the way you look - think about the things that you like about yourself. Stop worrying about living up to somebody else's ideal image. Who said you aren't ideal? It's best to just be you.

Loads of girls think that they are fat when they aren't really. They will make themselves ill dieting or not eating at all. It is best to avoid faddy diets, it's boring anyway. Just try and eat healthily and take more exercise. Work on the bits of your body you like. Loads of blokes do themselves in thinking they need to build up their pecs and stuff - girls like a bit of muscle in the brain department too you know!
