I've had to learn to fight all my life - got to learn to keep smiling. If you smile things will work out.
I meet people who say, "Girl, I watch every match, and I pray for you." I feel that energy and those prayers. Sometimes when I'm down on the court, in the back of my mind, I'm thinking, "They want me to win. Is there anything else I can give?" It encourages me to do better, to fight harder.
I can't become satisfied, because if I get satisfied, I'll be like, "Oh, I've won Wimbledon, I've won the U.S. Open. Now can I relax." But now people are really going to be fighting to beat me.
I'm not used to crying. It's a little difficult. All my life I've had to fight. It's just another fight I'm going to have to learn how to win, that's all. I'm just going to have to keep smiling.
I just never give up. I fight to the end. You can't go out and say, 'I want a bag of never-say-die spirit.' It's not for sale. It has to be innate.
