I think the people who have really followed my career from the time I was seven years old can see my steady progress and see the type of person and athlete I am.

I'm an Internet junkie.

My father wasn't really involved and my mom is the light in my life.

When I'm home, I'm relaxed.

You forget that sometimes people are out there to get you - they don't even have a reason.

I train so hard to make sure failure doesn't happen. If I do everything I can, and run as fast as I possibly can and someone still beats me, I don't think of that as failure.

I train harder than anyone else in the world. Last year I was supposed to take a month off and I took three days off because I was afraid somebody out there was training harder. That's the feeling I go through every day - Am I not doing what somebody else is doing? Is someone out there training harder than I am? I can't live with myself if someone is.
