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.

I think all tennis players have to struggle through the early stages of their career. We start off playing tournaments and really just get by. I always had a dream to play in the big tournaments and never have doubted if it was worth it. Having to battle a little early on in my career makes it all the more worthwhile now.

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.

Tennis takes care of everything. It requires agility and quickness to get to the ball, core strength to get power into your shorts and stamina to last for an entire match. In addition to toning your arms and shoulders, it's a total body workout for your legs and abs, and works your heart and core unlike any other sport.

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.

Control the things you can control .

You hear a few people saying that, you know, maybe some of the past male players like to watch me play or whatever else, just because I play a bit differently and maybe they can relate to it a bit more with a bigger forehand rather than a backhand, good serve and whatnot.
