There's a lot of great Olympians, but for me, I try to prove myself as one of the best - and that's the key thing.

I don't listen to music before a race - my coach doesn't like it, he thinks I might lose my focus and concentration.

I have to show who I am, play with the crowd, play with the camera. When people come to a race, part of it is the anticipation, "What is he going to do?"

I don't think limits.

Once a year I will clean my room, just because I feel I should.

The more success I have with track and field the bigger my brand is. So I would say I'm more of a brand now, trying to build for the future.

I am doing what I do [athletics] because the fans love it and it's a part of me, it's my personality. I think people come to see you run fast, but they also come to see a show, a performance. They want to see a personality, and that's what I give them.
