By the time I was 12 I was challenging every boy in our neighborhood at running, jumping, everything.

I don't know why I run so fast. I just run.

Never underestimate the power of dreams and the influence of the human spirit. We are all the same in this notion: The potential for greatness lives within each of us.

I believe in me more than anything in this world.

The triumph can't be had without the struggle.

The potential for greatness lives within us all.

Believe me, the reward is not so great without the struggle.
