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.

I want to be one of the greatest athletes ever to live, not only in track and field, but in all of general sport.

When I played football, I liked being a goalkeeper or a midfielder. I was probably better at cricket. I would be a very good cricketer if I was a professional now. I think I would probably have been the best, in fact.

I don't think limits.

There are things that bother me. I try not to let them, but they do.

I don't know the history of my sport. I'm not like those people who know everything.

My coach told me if I broke the national record for the 200, I could run a 100.
