Create a pre shot routine in three phases, one where you visualize, one where you align and one where you pick a key to initiate the swing
You might not have time to practice as much as a professional but you can have their set up in a matter of minutes, concentrate on keeping your upper body balanced on top of your lower body with your arms centered and not ahead of the ball
Although you might not know it you have the ability to control the distance on each of your clubs, use the numbers game to figure out how long you should make your backswing to hit each club whatever distance you want
