I feel like I'm always going to be me. It always goes back to being the person that I am. And I hope that will never change.

For me, there's a lot of expectations and you want to be able to live up to them.

I don't have a sprinter's body.

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.

Try to think of working out and healthy eating as a lifestyle. Rather than go on a diet or try a crazy exercise routine, try making them something you do every day.

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.

The pressure is hard. You get - the world is only watching every four years, and I think lots of people feel like they have to win in that time frame.
