Kids made fun of me because I was a slow learner, because I was hyperactive, because of a lot of things. Running gave me confidence.

Success isn't how far you got, but the distance you traveled from where you started.

I run to see who has the most guts.

A lot of people run a race to see who is fastest. I run to see who has the most guts, who can punish himself into exhausting pace, and then at the end, punish himself even more.

No one will ever win a 5,000-meter by running an easy two miles. Not against me.

Having a true faith is the most difficult thing in the world. Many will try to take it from you.

Something inside of me just said 'Hey, wait a minute, I want to beat him,' and I just took off.
