The most important lesson that I have learned is to trust God in every circumstance. Lots of times we go through different trials and following God's plan seems like it doesn't make any sense at all. God is always in control and he will never leave us.

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.

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

Every moment is not great and sometimes those are the moments in which you learn the most.

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.

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.

I'm always nervous. If I wasn't nervous, it would be weird. I get the same feeling at all the big races. It's part of the routine, and I accept it. It means I'm there and I'm ready.
