Retiring was hard. I'd spent 15 years doing something I loved, but when you get older everything seems to go. When I started spending too long with the physio and the doctor, I knew it was time to call it a day. But I had no preparation for being retired and I didn't know what to do.

I'm obsessive. I want to know the answer to how good I am. Most people aren't.

I am an education ambassador, mainly working with schools.

Having the ambition of becoming Olympic champion is a whole different ambition from wanting to be the greatest.

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

When we stage the Olympics it will inspire kids all over the country. A kid in Scotland or Ireland will be encouraged to take up sport.

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.
