Start where you are, use what you have.

Wherever I am when you feel sick at heart and weary of life, or when you stumble and fall and don’t know if you can get up again, think of me. I will be watching and smiling and cheering you on.

I don't care who you are, you're going to choke in certain matches. You get to a point where your legs don't move and you can't take a deep breath. You start to hit the ball about a yard wide, instead of inches.

I don't want to be remembered for my tennis accomplishments. That's no contribution to society. [Tennis] was purely selfish; that was for me.

Trust has to be earned, and should come only after the passage of time.

If I don't ask "Why me?" after my victories, I cannot ask "Why me?" after my setbacks and disasters.

I have always tried to be true to myself, to pick those battles I felt were important. My ultimate responsibility is to myself. I could never be anything else.
