There are several shots you'll work on; probably, if you're like me and many other devotees, you'll be trying to improve them for the rest of your life. Those shots are the backhand, the forehand, the overhead smash, the volley and the serve. No tennis player is ever fully satisfied with his or her performance (or if there is someone, I haven't met them yet), and most players are naturally stronger in one or two. In working on all of these, you'll need to develop a keen ability to keep your eye on the ball. That sounds easy but in fact is a skill that needs to be developed.

An acute, calm awareness of position -- where you, the ball, your racquet and your opponent are at any given time -- is what is the true essence of a great player, and that can take some work when the balls are coming at you fast and furiously. The real "zen" of tennis comes from being fully aware of your body position, where the ball is, and the exact moment of contact regardless of the type of stroke. Being off-center, running while swinging, not being in position and hitting the ball at the wrong time and in the wrong position are among the main reasons shots don't land where they should.

When you're waiting to receive a ball from your opponent, it is crucial that you be in the best ready position. To return the ball well you need good judgment and effective receiving skills. To develop them, start from an alert and stable ready position. Face the net with your weight on the balls of your feet and hold your racquet centrally, in order to allow easy play on either side of your body. Watch your opponent play the ball to anticipate its speed and direction. Stand with your feet shoulder-width apart for stability and with your knees bent to lower your center of gravity. Your weight should always be forward, as if you are a jungle cat waiting to pounce at any moment. The ability to move quickly in either direction is paramount, and you can't be caught flat-footed.
