Only advice I would give is to gradually increase your speed to maintain your control. The club head speed determines your potential. If you can only generate enough speed to hit it 150 yards, you won't score as well as someone who hits it 250. Make sure your left shoulder turns under going back as opposed to turning your shoulders too level to the ground. The feeling should be that when your arm and shoulders are going back, your lower body has already started to come down and through.
Slicers tend to swing the club too upright in their swing plane.
Strengthen your grip by turning your hands to the right. Take practice swings with the club up off the ground as if you were hitting a ball off a real high tee. From there you will feel a more rounded golf swing and a more natural release with your hands through the shot. I'm an 8 handicapper without any formal lessons. I'm wondering what I need to do to really achieve my potential.
