I try to lead by example.

One of the things we're trying to do more of is not just take money from corporate partnerships, but get more involved in the business side for when I retire. So Puma are going to make me an ambassador for life. I have a clothing line coming out. I am investing a lot in housing in Jamaica, buildings for rent.

I try not to eat too much fast food but still go for hot wings occasionally. As I get older, I have to pay more attention to my diet. My favorite food is jerk pork.

There's a lot of great Olympians, but for me, I try to prove myself as one of the best - and that's the key thing.
