If you're ranked number one in the world it's because you've earned it, and I think the only way to really get there is to have that ability and to have it nurtured in a very competitive environment at an early age.

You've got to believe you can win. But I believe respect for the fact that you can lose is what you always have to keep in mind so that nothing suprises you.

My accomplishments do not live up to my tennis game. Most people have to work really hard and win some big matches, and then they get money and popularity. For me it has been the reverse of everybody else. The exact opposite.

It's always been eclectic; you never know what you're going to get.

There's a lot of good waiting for you on the other side of tired. Get yourself tired.

A strong body listens. It obeys. A weak body commands. If your body is weak it tells you what to do. If your body is strong it'll actually listen to you when you tell it to do something. If you build it right you can overcome some of the obstacles of age and recovery.

The scoreboard said I lost today, but what the scoreboard doesn't say is what it is I have found. Over the last 21 years, I have found loyalty. You have pulled for me on the court and also in life. I found inspiration. You have willed me to succeed, sometimes even in my lowest moments, and I've found generosity. You have given me your shoulders to stand on to reach for my dreams, dreams I could never have reached without you.
