Professional tennis has become an extremely physical and unbelievably competitive sport. Injuries are the bane of tennis players, and it goes with the territory.

For some reason, every time I peak in my career, I injure myself. So, I'm constantly on the comeback trail.

You want to try and win as many slams as possible in your career. As a tennis player, that's what we always dream of as a kid, wanting to play slams, wanting to win them.

I have always believed that my job is to try and give my best on the tennis courts.

In my political career, I'd like to see a constitutional balanced budget amendment.

In the city, we work until quitting time. On the farm, we work until the job is finished.

You can no longer just be a good sailor. You have to be an incredible athlete as well. Having said that, you can be a great athlete, the strongest guy in the world, but if you can't anticipate and make decisions under stress and exhaustion and think ahead, then you won't be able to cut it, either.

I do not take to the field to defend myself from certain criticisms. If I do, in this kind of career, it is because I'm very self-critical.
