Billie: No matter how tough, no matter what kind of outside pressure, no matter how many bad breaks along the way, I must keep my sights on the final goal, to win, win, win -- and with more love and passion than the world has ever witnessed in any performance.
Billie: Victory is fleeting. Losing is forever.
Billie: Tennis is a perfect combination of violent action taking place in an atmosphere of total tranquillity.
Billie: I think self-awareness is probably the most important thing towards being a champion.
Billie: (On the Battle of the Sexes against Bobby Riggs) I thought it would set us back 50 years if I didn't win that match. It would ruin the women's tour and affect all women's self esteem.
Billie: (on tennis) I knew after my first lesson what I wanted to do with my life.
Billie: It is very hard to be a female leader. While it is assumed that any man, no matter how tough, has a soft side . . . any female leader is assumed to be one-dimensional.
Billie: The trouble with being number one in the world - in anything - is that it takes a certain mentality to attain that position, and that is something of a driving, perfectionist attitude, so that once you do achieve number one, you don't relax and enjoy.
Billie: Winning is very tangible, it's very exciting, it's very pleasing, but it's momentary. If you can do things that last, that each generation can build upon, then that's when you're cooking.
Billie: I . . . like being successful. I somehow always knew that I would succeed. I had a great sense of destiny from the time I was very young.
