I started mountain-bike riding two years ago, which is much better than riding a stationary bike in the gym. Mountain biking is a total body workout.

I did always dream of being a professional player. I think every kid does dream of being a pro, but to last the journey you have to love tennis as a sport and if you are lucky enough to make it in the pros, it is really a bonus.

That $27,000 that a young player will now get just for making the main draw at the Australian Open is huge. It can set them up for a couple of months which at that level you really do need that kind of help. It sounds like a lot of money, but when you're travelling the world trying to make it as a tennis player, it doesn't last long.

I get my drive and determination from just winning and playing tennis. I know if I don't work, I won't get rewarded. It was a life long dream to win a Grand Slam so when I was able to do that it felt so good and I wanted to do it again. It's not that hard to stay motivated.

It is never too late to get into tennis! While I started playing at the age of 8 when my parents gave me a tennis racquet for Christmas, tennis is a lifelong sport that can be enjoyed by people of almost any age. It's also something you never forget once you learn.

I think I will always stay involved in tennis and would like to give back by helping out young players. I have done a little commentary and may one day enjoy doing that again.

I love anything that involves the ocean. Swimming, snorkelling or surfing are all fun, which distracts from your mind that you are actually doing a workout. Being outdoors in the sun and the salt water is great for freeing your mind and feeling alive.
