For kids it's natural to be competitive.

Sometimes you have to resist working on your strengths in favour of your weaknesses. The decathlon requires a wide range of skills.

It's good to be difficult to know. Too many people are too easy to know.

I am only about winning and getting better.

I've still got a small fitness and conditioning business where I travel round the world doing stuff for individuals and corporations, mainly fitness training.

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.

People don't want to serve apprenticeships any more. Kids expect to be paid and treated really well and all that guff before they've achieved anything. It doesn't work like that. You have to spend five or six years being relatively rubbish and put up with it. For that you don't deserve to be getting lottery money.
