You can find flaws in Agassi and Sampras, but Federer has none.

You're playing or you're not playing. If you're playing, so just shut up and play.

You cannot change me; this is the way I am.

You have to wake up and you have to run if you want to survive.

If you're losing, just be a man; be a man and lose as a man.

No matter what happens, tennis is still tennis: You can see a lot of great matches, a lot of new people.
