“I always say that when I’m playing well, no one can beat me. I’m not just saying that to sound full of myself or anything, but it’s true.”

If anything, you know, I think losing makes me even more motivated.

You have to believe in yourself when no one else does.

I don’t have anything to prove ever, ever in my life. If I have something to prove, what does that mean for everyone else? And I think everyone should have that attitude.

I’m not one to blame anyone else for anything. And I don’t think anyone else should either.

Victory is very, very sweet. It tastes better than any dessert you’ve ever had.

I don’t go thinking I’m going to lose. I never go into a tournament thinking that. I’ll do the best that I can.

I think in life you should work on yourself until the day you die.

Everyone’s dream can come true if you just stick to it and work hard.

I wanted to get really fit. I wanted to lose some weight. So I’ve been doing Pilates and yoga, trying to lean out my body so I won’t be bulky.

I’ve had to learn to fight all my life – got to learn to keep smiling. If you smile things will work out.

I think you have to love yourself before you fall in love. I’m still learning to love myself.

Growing up I wasn’t the richest, but I had a rich family in spirit. Standing here with 19 championships is something I never thought would happen. I went on a court just with a ball and a racket and with a hope.

I love tennis more than designing because it’s actually easier and I don’t get nearly as nervous.

You can’t underestimate anyone.

My dad is the nicest guy you’ll ever meet, and the easiest going.

I really think a champion is defined not by their wins but by how they can recover when they fall.

I have great faith in fools – self-confidence my friends will call it.

It is not so much our friends’ help that helps us as the confident knowledge that they will help us.

I don’t like to gamble, but if there’s one thing I’m willing to bet on, it’s myself.

Our future is our confidence and self-esteem.

I am so confident in that idea that if love gets a chance, it will transform the community and the world into a more prosperous place, because we are capable of love.

My drive and passion will outweigh your hate! Nothing you can do to stop me. You only help me!

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.

If you are not the best, then pretend you are.
