Greatness is defined by someone who is not simply awesome and wonderful in the sport they compete in but goes beyond that and is great in whatever they do off the track or off the court.

I did pretty well at the Sydney Olympics, but those were my first Games.

I've never worked a day in my life. Don't get me wrong. I work at track. If you love what you do, it's not work.

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

I loved having my baby inside of me, but I was very happy when he was finally here.
