Worrying gets you nowhere. If you turn up worrying about how you're going to perform, you've already lost. Train hard, turn up, run your best and the rest will take care of itself.

As long as I'm in good shape, you'll always see me smiling.

I can't really live outside Jamaica. I can be away, but only for a while.

The hard part for me is rest. I am a person who stays up late. If I go to bed early, I don't sleep, but I know I have to rest. That is always a struggle for me.

When I was young, I didn't really think about anything other than sports.

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 don't have a clue. These things don't bother me. I think about the technical stuff but not how many steps or what my heart rate is.
