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.'

The only limitations are mental. The guy who thinks positively will win.

If you work hard in real life, people tend to get in your way - either from inertia or prejudice - and they stop you achieving things. It's the worst thing about real life compared with sports, where you generally get what you deserve: if you're the fastest guy, you win; there are no other games being played.

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.

You can be an Olympic champion in 9.5 secs, but to be the greatest, there's more to it. It takes a bit of forethought and a lot of mental application.

Sport and health are so important to our nation that they deserve to be right at the front of people's minds.

I did not want to be the best black man of the year; I wanted to be the best man of the year.
