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.

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.

In tennis it's easy to get greedy - and one Grand Slam doesn't feel enough any more.

Control the things you can control .

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 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.

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.
