1, Do not use your weight to measure your self-worth. Your self-worth is the sum of everything that makes you special and unique - not just your thigh and waist measurements! Add up your assets, talents, how you treat others, how you treat yourself, the contributions you make to your family, friends and community. Now you have self-worth.
2. Eject the negative tapes which continually plays in your mind. Eject them and insert new tapes. You may have to make a conscious effort. When the critical tape starts playing, picture yourself hitting the "stop" button and insert a new, positive tape.

3. Count your blessings. You have a lot of things to be thankful for a home, a loving family, friends you enjoy, a job, a sunny day, the knowledge you've acquired - even things like shoes, a coat. Many people don't have these things. A mind that counts blessings has no room for self-pity.
4. Don't use "all or nothing" thinking. No one is a "total" failure. Most things you do right. Just because you sometimes make a mistake or take a wrong path does not make you a "total" failure. It makes you human.
5. No one starts from zero. You probably eat pretty well a lot of the time. We can always make improvements, but consider the glass half full, not half-empty.
