There's no day when I don't think it would be great to be 25 years old and have the Olympics coming in less than 300 days - and be the best in the world. I can't think of anything so motivating.

Athletes these days are too robotic. People like to see performances filled with emotion. In my career I tried to be amusing, to differentiate myself from the other champions.

When you're walking into the stadium, you just say to yourself, 'the 100m is the same anywhere, the shot put is the same weight anywhere.'

Most people doing the decathlon these days are quite boring, so people don't relate to them.

In my heart of hearts my motivation would always have been to be the best, and I think that athletics is probably what I was built for.

There were only ever two black kids at my school. I never considered myself to be 'a black kid'. I was who I was. Which isn't to say things haven't happened to me that wouldn't have happened if I wasn't black.

But if kids take up things like hockey and football they will go back to it.
