Champions take responsibility.

I like entrepreneurial people; I like people who take risks.

I think it's really important to have portion control. I don't believe in losing weight quickly.

Men can have a huge turnover of sponsorship and still survive a lot better than the women. But the women's ratings are better, at least at home in the United States than in the men's tennis.

I think one of the concerns, anytime you're in the human business, like sports, it's a very high - risk endeavor. You do have to get players every year. You have to deal with calendar. You have to deal with all kinds of things in our sport, like every sport does.

Natural talent only determines the limits of your athletic potential. It's dedication and a willingness to discipline your life that makes you great.

A champion is afraid of losing. Everyone else is afraid of winning.
