I was very disappointed (at the U.S. Open), and I went out there and I worked really hard.

If I'm nervous, it means I had to work hard to get there, whether it's playing in a tournament or speaking at an event. So I try to stop and be proud of getting to live in that moment.

It's easy to impress me. I don't need a fancy party to be happy. Just good friends, good food, and good laughs. I'm happy. I'm satisfied. I'm content.

Women's tennis is getting faster and the girls are getting more athletic, so I need to push myself to become a better athlete. I think 2013 showed me, like a few other years how important being healthy is and how I must listen to my body. During this off season I have been a little smarter on how I train and how I treat my body.

I've been playing against older and stronger competition my whole life. It has made me a better tennis player and able to play against this kind of level despite their strength and experience.

I don't need many things. I don't need glamour and attention to be happy. I'm very happy being settled and working my butt off and trying to win grand slams.

That is what is most special about achieving equality - the positive signal that it will send the world over to the next generation of girls dreaming of winning Wimbledon or becoming a scientist or going to the moon as an astronaut.
