Being famous before you've formed your personality, before you have that self-esteem, is dangerous.

I realized that with hard work, the world was your oyster. You could do anything you wanted to do.

In tennis, at the end of the day you're a winner or a loser. You know exactly where you stand... I don't need that anymore. I don't need my happiness, my well-being, to be based on winning and losing.

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

Being famous before you've formed your personality, before you have that self-esteem, is dangerous.

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.

If you can react the same way to winning and losing, that's a big accomplishment.
