People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

I think Serena Williams is the best tennis player of this generation, if not the best ever. It is amazing for her to be playing as well as she is at the age of 31.

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'm not the first player to have their home Grand Slam and not perform. There have been a few Australians and French players, you name it. It's a tough thing. But it is one of those things. Would I rather have a Grand Slam in my country than not? I would.

When I'm playing my best, like I was at the U.S. Open, I feel on top of the match and able to do exactly what I want. There are other times when you're not in control, but that is tennis and you have momentum changes in every single match.

My workouts include aerobic exercise for a healthy cardiovascular system; strength training to maintain muscle tone and bone density; core strength exercise for a stable mid-section; and stretching to maintain mobility.

Control the things you can control .
