"Most of the limitations you think you have are the ones you have decided on. They are often entirely self-imposed. You might think, 'I can't do this, I can't do that, I would never do that, my parents could never do that, I never played baseball, I never climbed a mountain, I never, never, never'... It's the old broken record in your head. Throw out that negative thinking right now! Learn to play a positive message in your head because it's all about attitude."
