“There’s no promises in any entrepreneurial business. You have to really work hard every year and also try to envision where you want to go in the future at the same time.”

Winning comes down to who can execute under pressure.

You’ve got to win in sports – that’s talent – but you’ve also got to learn how to remind everybody how you did win, and how often. That comes with experience.

When I was playing, we didn’t have to compete against everybody in the world. Now it’s a truly global sport, so the competition’s much greater, just like it is for our children in every other area, whether it be in science or technology or whatever you talk about.

Don’t worry about what people say.

Being Number One isn’t everything to me, but for those few hours on the court it’s way ahead of whatever’s in second place.

Tennis is a perfect combination of violent action taking place in an atmosphere of total tranquillity.

I knew after my first lesson what I wanted to do with my life.

Don’t go into debt and don’t spend a lot. It’s not how much money you make, it’s how much you spend.

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.

Marriage isn’t a 50-50 proposition very often. It’s more like 100-0 one moment and 0-100 the next.

I like to see what future generations are thinking about.

Pressure is a privilege – it only comes to those who earn it.

In 1973, women got 59 cents on the dollar; now we are getting 74 cents on the dollar. In the area of finance and business, we are at 68 cents on the dollar.

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.

The main thing is to care. Care very hard, even if it is only a game you are playing.

When we reach the point where the women athletes are getting their pick of dates just as easily as the men athletes, then we’ve really and truly arrived. Parity at last!
