There will always be nay-sayers. People who will tell you that you can't accomplish what you have set out to do. Prove them wrong.
When you feel like reaching for that chip, that candy bar or that fast food, listen carefully......remember their voices. Prove them wrong.
If you think you can not walk another step, run another lap, dance through another song; when you feel like there is no more of you to give.....remember the people that told you it was not possible. Prove them wrong.
Prove them ALL wrong.
