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

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

The decathlon takes so long to learn that people who are good athletes don't want to go back to the beginning again.

I didn't even know what it was when I started. But I was lucky. I found it at 16. Most people don't discover decathlon until they're 21 or 22.

I think one of the things about being a good coach is to recognise when you have given all that you can. In fact there should be some sort of unspoken law that says that a coach cannot have anyone for three or four years - if you have not passed on most of the stuff you know in that time, then you are not doing a good job.

You can be an Olympic champion in 9.5 secs, but to be the greatest, there's more to it. It takes a bit of forethought and a lot of mental application.

There are lots of women tennis players, for instance, but because not many of them seem to have much personality, they're interchangeable. You don't have a feeling about them.
