Are you the player in doubles that wishes that your opponents would not hit the ball to you? On the other hand, are you the player that cannot wait to hit the ball? If you wish to be the latter, you must go to the ball. Imagine how you must move to every ball in singles. Think this way when you are playing doubles. Always make your opponents think you are anxious to hit the ball. Try to make some move (either with your feet or with your racket) to every ball.
Many of my students say, "If I make a move to the ball I will distract my partner." Quite the contrary, by moving to every ball your partner will get used to it and start watching the ball (which is everyone's job). The distraction to your opponents by your movement far outweighs the inconvenience to your partner. If you move to the ball and fail to hit it, remember to get out of your partner's line of fire and return to a defensive position. Going to the ball is where all the fun is.
Good luck on the courts!
