Before a race, I block out what's going on in the stadium. It's different for everyone. But for me, I've always been able to block it out. For a sprint race, it's important not to get distracted.

I had worked so hard; that was my opportunity. And my mom was just able to turn it around for me. She helped me to be able to see the other side of things and that this is not the end for me.

I think every genius person has a bit of insanity.

Everyone sees the glory moments, but they don't see what happens behind the scenes.

My speed is a gift from God, and I run for His glory. Whatever I do, it all comes from him.

It was all kind of a whirlwind at the beginning. I didn't really realize that I had a special gift from God. It was probably towards the end of high school in my senior year when things really started to come together and I realized that I had more potential and that I could do this as a career and that the Olympics were a possibility.

I always look back to my first Olympic medal in 2004 in Athens. I was very new to the sport, and it was my first big win at the Olympics.
