A woman told me, "You'll never lose all that weight. It's just too much to expect. I know I've tried and nothing works."
I went away feeling like I was wasting my time.
Then I found this from Mark Twain -- "Stay away from those who would belittle your ambitions. Small people always do that, but the really great make you feel that you too will become great."
Keep the petty people at arms length and surround yourself with greatness!
