Even sleep is part of my job because I need a certain number of hours of sleep to be able to train at the intensity that I do. I'm constantly working to keep my body in the best possible shape.

I'm very hard on myself. Sometimes too hard on myself. When I lost in the Wimbledon finals, I was so sad, I cried. I had the runner-up trophy! It's still a great accomplishment, but I was so mad.

After they lose, I think all tennis players go back to a specific part of the match where they wish they had done something different.

I love going to the beach and swimming in the ocean. I think it's so relaxing. It's also a great form of active recovery. It's perfect for those rest days when you still want to move a little bit.

Have I ever pretended to be something? I think back in college I think I might have told a girl that I was a professional tennis player once. And then, of course, she had never heard of me so I had to dig deeper. 'I'm just sort of on the playing satellites. You know, I'm kind of working my way up. I'm not ranked in the top 100 or anything.'

It's very hard to argue with someone who thinks he is God because he makes a lot of money.

The Obama administration likes to say that it is 'pro-worker.' But something is amiss when its labor priorities are forcing unionization and labor contracts on American workplaces, and denying union members information on how their dues money is spent.

We all have something about ourselves that we'd change if we could in a perfect world, be it our body image, our financial status, our relationship, whatever. I wanted to talk about how nobody's exempted from the realities of life and all those things.
