"Working to change things gives me the most long-term happiness. Performing is very temporary. To me, winning is doing what I want, what makes me happy, doing the best I can at this given moment in my life. That’s all I can ask of myself. If each person does the best with what he has, that’s winning. He’s fulfilling his own potential." 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.
