I always want to give more than I gave yesterday.

I try to think about my goals. I think about my competitors-I know they're working hard, and if they are, I have to work hard too. I have to be one step ahead of them.

I focused solely on the sprints, dedicated my time there, got in the weight room, just really did everything I could to make sure I would be in the best position to run for gold.

My dad's a pastor and a seminary professor, my mom, she has such great faith.

I myself am frustrated in just where sports are at. It's a hard thing when you're out there working every day, and you know that someone else is cheating and they may not necessarily get caught.

I majored in elementary education, and I have a passion for kids.

And as long as I'm passionate about the sport, I'm able to do that and I'm happy, then I would love to do another Olympics. I'm just going to see how I'm feeling.
