Take care of your body. When you make an effort to keep your body in good working order, you'll not only feel better physically, but you'll also feel a sense of pride. Respecting your body also means not insulting it for what it is, naturally. Make an effort to get fit and stay healthy, but don't trash yourself over the things you can't control, like your proportions. Focus on the things you can change and improve, and do it because it feels good, not because you think you're not "good enough" the way you are. This doesn't mean that going to the gym and looking amazing will automatically lead you to have high self-respect. But it does mean that if you don't put any time or care into your appearance, that you'll start to lose respect for who you are.
