You don't have to be on the tennis court to work on your game. There are many ways to do that. You can work on your swing without a ball and you can also work on your physical ability in the gym or even sitting in the classroom by squeezing a ball to develop your wrist.

Watching tennis on TV can be a great way to learn, looking for patterns, imitating the pros and listening to the commentary can be very useful. Visualization is another way of improving; simply imagine yourself playing perfect shots and winning points, replaying past marches -- only good matches -- in your mind can get you in a zone. It's a good mental exercise.
