That match was late evening and I had the experience of the electricity of the Centre Court because it was packed, a full house for the whole match. It had been a great year for me, first time there and I had the full taste of Wimbledon.

There was kind of a code that you had as an Australian that you never left the court losing unless you had blood all over you. That's the sort of toughness you need to compete on the world stage and I feel that our kids today just don't have it.

So there was a fire inside me. And that fire inside you, it can be turned into a negative form or a positive form. And I gradually realised that I had this fire and that it had to be used in a positive way.

By the time I got to the hospital, I certainly realised that I had a problem because I couldn't write or print at that time, which lasted luckily only about four months. I'd gone numb here and on my tongue and the right foot a little bit.

People think this is all about the top players hitting tenins balls and they talk about technique and strategy and how important that is. But they don't understand the essence of competition. This is one-on-one, two players out there fighting each other with everything they have, trying to bring the best out of themselves. And the difference at this level of the game is all in the head and in the heart.
