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.

Whoever has played tennis knows the court is pretty big and you always have space to put the ball in.

The grass is a very big challenge for me. There are these low bounces and different movements, which is very difficult, especially for my height and weight. When the surfaces change, and I start to play on grass, I start to feel it in the lower back and the lower hamstring.

I can see that the tennis for the fans could be a bit boring, and these days you have these new modern things which you can do, and you have a lot of time, because you just play a match, and practise, and many times in between you can bring many things to the fans.

I exercise, walk a lot, and break into the occasional trot. I also lift weights three days a week, and I like to read about what makes a good diet. Overall, I do follow a healthy lifestyle.

I've got to be honest and say that, growing up, I wasn't a big sports guy, but I love the camaraderie. I just love people getting together, fighting for a team and getting super-emotional about it.

I never smoked in my life. Neither did my mother. And so many women I meet whose mothers or aunts or whoever who have gotten lung cancer were no-time smokers.

All I suggest is to make K-12 like higher education. Higher education in the United States is the best in the world because these institutions compete with each other for your tuition dollar. Let's just bring competition to public education.
