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

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.'

I tend to eat vegetables only when I'm with the kids and the rest of the time, I'm a bit slack. But, I am weight-conscious, so I concentrate on avoiding junk food.

What used to drive me was the fact that I wanted to be better than everybody at something. One of my best qualities is that I used whatever other people found to be an adverse thing to be a positive thing for myself.

We crave instant success these days. If you are a really good sprinter and long jumper, you don't want to spend two or three years on a whole new set of events. You're used to doing well and it's difficult to give that up.

I am an education ambassador, mainly working with schools.
