Many golfers focus too much on accelerating the club through the ball, usually because it's been drilled into their heads. This might guard against quitting on the shot, but it often leads to a short backswing and too long a follow-through (left). That means you've over-accelerated to the finish. All sorts of problems can result, like fat and thin shots and a lack of feel because the club is speeding out of control. Instead, make a little longer backswing and let the weight of the club accelerate into the ball, with the grip end leading the clubhead.
