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

I don't consciously try to be a role model, so I don't know if I am or not. That's for other people to decide.

What do you do after you are world-famous and nineteen or twenty and you have sat with prime ministers, kings and queens, the Pope? Do you go back home and take a job? What do you do to keep your sanity? You come back to the real world.

I believe in me more than anything in this world.

Winning is great, sure, but if you are really going to do something in life, the secret is learning how to lose.

I loved the feeling of freedom in running, the fresh air, the feeling that the only person I'm competing with is me.

Sometimes it takes years to really grasp what has happened to your life.
