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

I don't have a sprinter's body.

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.

Before a race, I block out what's going on in the stadium. It's different for everyone. But for me, I've always been able to block it out. For a sprint race, it's important not to get distracted.

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

I definitely think I put more pressure on myself. I can be hard on myself and super-critical and very rarely satisfied or happy. I am my biggest critic.

Competing at the Olympics is the pinnacle of your career. Everything is amplified, and you feel so proud to represent your country. You're there with athletes from all over the world. Everyone is coming together, putting differences aside.
