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 never let track define me. That's something that's really important to me. That's what I do and it's what I love, but I think by having other things I'm passionate about and interested in, it helped me to come back. It helped me to have renewed love for the sport by being able to step away and then come back.

Right now I'd say my favorite fashion designer is Zac Posen.

There are moments that aren't great. And I think it's amazing for people to be able to have some insight, to be able to see the support system and what really happens.

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 am a big believer in visualization. I run through my races mentally so that I feel even more prepared.

I'm passionate about my sport and grateful that I get to do it for a living.
