Appreciate all that your body can do. Every day your body carries you closer to your dreams. Celebrate all the amazing things your body does for you—running, dancing, breathing, laughing, etc.
Remind yourself that "true beauty" is not simply skin-deep. When you feel good about yourself and who you are, you carry yourself with a sense of confidence, self-acceptance, and openness that makes you feel beautiful regardless of whether or not you physically look like a supermodel. Beauty is a state of mind, not a state of your body.
Look at yourself as a whole person. When you see yourself in a mirror or in your mind, choose not to focus on specific body parts. See yourself as you want others to see you—as a whole person.
Surround yourself with positive people. It is easier to feel good about yourself and your body when you are around others who are supportive and who recognize the importance of liking yourself just as you naturally are.
Shut down those voices in your head that tell you your body is not "right" or that you are a "bad" person. You can overpower those negative thoughts with positive ones. The next time you start to tear yourself down, build yourself back up with a few quick affirmations that work for you.
Wear clothes that are comfortable and that make you feel good about your body. Work with your body, not against it.
