I feel like I'm more a fan of tennis rather than it being men's or women's. I enjoy watching doubles as well when it's on. I think that there are certain players that I enjoy watching on the men's and women's side. There's some players that I don't enjoy watching on both sides.

I just enjoy watching tennis. And there's things that you can learn from the men's and the women's game.

Earlier in my career, I used to spend a lot of time practising my tennis on court. Now I've learned that it's better to do just a couple of hours on court and two gym sessions a day. That's what's made me fitter and stronger.

My speed is something that has made a difference to my whole career. When I've felt quick and I'm moving well, it makes a huge difference to my entire game. When I feel a bit slower, I end up doing a lot more defending. When I'm a bit quicker to the ball, I feel I can attack a lot more.

I could have been banned. That's what I was most scared about. All the hard work being for nothing. It was basically my livelihood and my sport being taken away from me. It was everything.

When you're young and idealistic, you don't care: you'll play to no one, in your bedroom - like kids with football - you'll play anywhere; you just love the music. And then, bang - soon as you're in the industry, you think that's the dream. But that's when the dream starts to end.

When I was in Birmingham I used to go to a place called Redwood Field. I used to get there for a two o'clock game. Where can you make this kind of money playing sports? It was just a pleasure to go out and enjoy myself and get paid for it.

I want young kids to play tennis because of me.
