Losses have propelled me to even bigger places, so I understand the importance of losing. You can never get complacent because a loss is always around the corner. It's in any game that you're in - a business game or whatever - you can't get complacent.

I am someone who likes to stay positive.

If you give me a short shot I will attack you. I'm not a baseliner who rallies. I try to get the point over with.

Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.

Life is challenging but I'm always up for a challenge.

Unfortunately the world is what it is now. People don't get along for whatever reason. As professional athletes, in a way we're almost ambassadors for peace, because sports brings everyone together.

Grand Slam losses are hard. I treat myself after losses though, I usually go to McDonald's and I have a hamburger and you know, something. Because you know, you just need to be nice to yourself sometimes after the loss.
