"I do something because I want to do it, not because I feel a sense of responsibility. Sacrifice is doing something you don’t want to do. Yes, I get tired, cross, lose my temper, get ticked off, and sometimes I don’t feel appreciated, but as I told the women players when we started with Gladys and Joe, “If you think that we’re going to be appreciated ten years from now, I got news for you. You should get joy and gratification out of it now. You know that you’ve done it. If that isn’t enough for you, don’t bother.” Billie Jean King -- Particular Passions: Talks With Women Who Shaped Our Times, By Lynn Gilbert. The oral biography of Billie Jean King from her days on the court.
