Find something that you're really interested in doing in your life. Pursue it, set goals, and commit yourself to excellence. Do the best you can.

I'm not getting within 20 feet of a married man ever again - not even talking to one!

Single-mindedness. I hate to say it because I don't think it's the best thing for developing a person, but the single-mindedness - just concentrating in the one area - that's what it takes to be a champion.

You've got to take the initiative and play your game. In a decisive set, confidence is the difference.

Whatever your goal in life, be proud of every day that you are able to work in that direction.

Of all my achievements in tennis, I'm probably as proud of my record on clay courts as any of my Wimbledon, U.S. Open or French singles titles.

I can definitely say the same thing [discussing Steffi Graf's claim that she had played against at least one top player who used steroids]. Steroids can really make a difference, physically and mentally. I'd be really disappointed if I had been ranked No. 2 behind someone who took steroids.
