I like to have fun, just stay relaxed.

You can't really give away anything in your book ... should be exciting, it's my life, and I'm a cool and exciting guy.

I want to stay involved in athletics; I want to encourage kids to take part and try to grow the sport.

I think sometimes, when you're on top and all you do is win, win, win, win, win, you get lazy and lose focus. When you lose it opens your eyes and you get serious. There is always a time when it is good to lose, at the right time for you.

We Jamaicans are not so much stressed about time, you know, but you have to stay on top of it. And, of course, on the track, every time we go on the track, it is all about the seconds and the fractions of a second that count.

People always say I'm a legend, but I'm not. Not until I've defended my Olympic titles. That's when I've decided I'll be a legend.

It's a great feat for me to have broken my world record.
