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 often find that pundits are quite negative... not just in tennis, but in sport in general. I just don't like that. Obviously, the job of a pundit is to create interest and a bit of controversy. I get that. Listeners like that. But I do think there's a duty there to promote the sport and talk about how good these people are at what they do.

I never thought I'd make the pages of 'Sports Illustrated', because I've always been skinny.

If I could be good at any sport, it'd be javelin. I know a few people I would love to throw a spear at.

I cannot do a better job than a journalist. I cannot do a better job than politicians - what I can do is play my football.

My mom has never cared if I did sports or not. Obviously, she's proud of me, and she loves the fact that I'm an Olympian and she's got these trinkets to hang around with the medals and whatnot. But if I wanted to do whatever, if I wanted to be a doctor or a lawyer or whatever, she was going to support me regardless.
