But the problem with coaching is that it is a full-time job. By that I mean for at least 40 weeks in a year you have to be with the player, either travelling or training. Right now I don't want to do that.
But in 2000, the injuries really started to kick in and my elbow gave a lot of problems. At the end of the year I had to take 20 months off before I could come back into the game.
For me, and most of the other players, too, if you had to pick one of the four Grand Slams, you would pick Wimbledon. It's got tradition, it's got atmosphere, and it's got mystique.
I had a lot of different thoughts and ideas and always to transform, but I'm trying certain things that I feel my heart is really going for and that was one of the things that I initiated a few months ago.
I think I can win a slam. That's my main goal, and if I could choose one, then yes, it would have to be Wimbledon. But, honestly, I would take any one of them.
I always call 'Billy Elliot' a fantasy autobiography because I never wanted to be a dancer, but I got a lot of stick from the other kids about wanting to be a writer and being interested in drama.
When the headache persisted, I checked myself into an emergency room. When the doctor used the term 'brain tumour', I feared the worst. My whole world shrank around me.
I have to use other things to help my tennis, like my brain. But I believe that, even when your muscles are not so fast, with the brain and with concentration you can compensate.
Maybe something is wrong with me, but I just think I'm normal. I'm not super-skinny but I'm not super-fat. But I don't really care about what other people say.
It's hard to think what should make your blood boil more - what happened to Billy Ray or what didn't happen to those who abused him. It's something we can't ignore.
I grew up on the tennis court with lots of other kids. There were like 40 kids all afternoon and I was one of the youngest ones, so I always had to chase everybody to keep up.
The top players talk more now, and we have more meetings. We're just trying to get things better. But we still need somebody who could make a difference.
As a tennis player you can win and you can lose, and you have to be ready for both. I practised self-control as a kid. But as you get older they both - winning and losing - get easier.
My goal is to improve my game, stay healthy and be competitive. If I have that, I know I can be able to win tournaments, which in the end is what it counts.
I think I am a complete player. I can play well on all the surfaces. For me, the clay might be easiest, but I am not a specialist on clay.
My tennis is aggressive, though I wouldn't say that it's more physical than technical. I rely more on technique than physique, but being physical is always a help to me.
I was a baseball player at North Central High School in Spokane, Washington even though I was all-city in basketball, even when I signed a letter of intent to play quarterback at Washington State.
I listened to Billie Holiday a lot in order to learn to sing. She remains one of the extraordinary jazz singers. But my intent is to become my own voice, to be able to interpret these songs in my own way.
It doesn't matter who is playing or how old they are. I just worry about what I can control. It doesn't give me more or less motivation.
If you look at tennis, the girls have become much more attractive; they wear makeup. In my generation, you were a tennis player. It wasn't like you had to look a certain way.
Often people ask how I manage to be happy despite having no arms and no legs. The quick answer is that I have a choice. I can be angry about not having limbs, or I can be thankful that I have a purpose. I chose gratitude.
