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

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.

I think it's very important, even if you're not in organized sports, but just to be active, to be healthy.

I spend around two and half hours on the track every day running and another 2 hours in the weight room lifting weights with my strength coach.

Jackie Joyner-Kersee is actually someone I have a personal relationship with and who continues to do amazing things in her community. I continue to be inspired by her. If I can emulate myself after someone it's her and I just hope to have that effect on my community and continue to go on to do things like she has.

My mom always has this amazing ability to always see the best in a situation. In that moment [when finished 2nd in the 200 meter race in the 2008 Olympic games] I was just completely devastated. I mean, I had worked so hard; that was my opportunity. And she 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. She's just an amazing supporter and an encouraging person and she has a unique ability to do that. And so those are the kind of things she said to me in that moment and over the next four years. When things get tough, she's always been my strength.

I grew up in my mom's third grade classroom and always helping her, and I also got a passion for kids that way.
