I'm just competitive. It doesn't matter what it is. I want to win.

What's really heavy on my heart is fighting physical inactivity.

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 mom is great and I make sure that we pray together before every race. She helps me put everything in perspective and remind me of the real reason I run.

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.

You know, I love wearing heels. I wish I could wear them all the time, but, you know, my sport doesn't really permit it.

I want to run for eternal glory and track is great, but it's not what life is all about.
