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.

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.

A lot of women say they love being pregnant, but I wasnt such a big fan.

I will continue to express the fact I am for a drug-free sport and always will be.

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

I recognize that by saying that I'm deeply sorry, it might not be enough and sufficient to address the pain and the hurt that I have caused you. Therefore, I want to ask for your forgiveness for my actions, and I hope you can find it in your heart to forgive me.

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.
