Few of us are granted the grace to know ourselves, and until we do, maybe the best we can do is be consistent.

In tennis you're on an island. Of all the games men and women play, tennis is the closest to solitary confinement.

I've been cheered by thousands, booed by thousands, but nothing feels as bad as the booing inside your own head during those ten minutes before you fall asleep.

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.

You'll hear a lot of applause in your life, but none will mean more to you than that applause from your peers. I hope each of you hears that at the end.

Tennis was always sort of a - a learning. It was a vehicle for me to discover a lot about myself. And the things that I sort of discovered at times I not only didn't want to see it for myself but I certainly didn't want millions of people to see it.

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.
