Watch Jack Nicklaus and Tiger Woods on TV and you will see one thing they do on EVERY single shot they hit. Before you read any further, do you know what that is?
You will never see Tiger Woods hit a shot without seeing his eyes working back and forth between the ball and his intermediate target.
He always picks out that spot in front of the ball by several feet and directly on his target line. He works on lining himself up based solely on that spot, the actual target is secondary until he is comfortable with his alignment in relation to his intermediate target.
You should do the same, and do it on EVERY single shot.
Learn to line up with an intermediate target and you will improve the consistency of your shot making. It's that simple.
