Most golfers feel like aim is their number one problem, but really it is hitting the golf ball straight. It’s hard to find the correct aim if you have curvature in your golf ball because if you slice the golf ball it will slice more with your driver than it will with your 9-iron, and then aiming becomes very difficult. Provided you hit the ball pretty straight, then obviously aiming is probably the most important thing there is in golf. Here is a little tip on how you can work on it. Put two clubs down, one on your feet and one along the ball line. Try to line up your feet, knees, hips, shoulders, eyes and arms all parallel to the left of your target line. I talk about two things when I talk about aim; I talk about aim and alignment. Alignment is making sure that all your body is coordinated: feet, knees, hips, shoulders, eyes and arms. The most important in that group are your eyes, shoulders and arms. Getting them aligned up so that everything is coordinated well, parallel to the left of your target. Once you have your alignment, then you can find your aim. Turn your alignment so that you are parallel to the left with your body and right on it with your clubface. The bottom edge of your clubface should aim directly to your target. That is how you find your aim, and that is how you find your alignment.
