I think everyone deals with things in their own way. Everybody's different. My family are all different. None of us are the same. We all deal with different things in different ways. I think it's about knowing yourself, what pushes your buttons, and figuring out how to work with yourself.

As long as we're fit, we just have so much to give on the court.

To be a well-rounded person and know what's going on in the world around you, to have a perspective outside of your sport, is important for every athlete. I'm blessed that our parents gave us that.

The thing about tennis is if you stay off for two weeks, or just for three days, you can lose your rhythm quickly. So it's just a question of constant diligence and vigilance.

Losses have propelled me to even bigger places, so I understand the importance of losing. You can never get complacent because a loss is always around the corner. It's in any game that you're in - a business game or whatever - you can't get complacent.

My motto has always been that you can't say, 'Oh, it won't happen to me.' You have to say, 'That can happen to me.' So always be aware that things can happen.

I don't want to give anyone an edge in my mind. Every time I walk out on the court, I have to feel I'm the best so I can compete well. A lot of times, my chief rival is just me.
