When you start playing golf, you have to learn the basics: how to hit the ball, how to get the ball in the air, how to putt, how to chip. Getting lessons on these basics is the best way to learn them, and you should keep taking lessons on these skills until you’re fairly good at them. “Fairly good” means that more often than not, you know here the ball is going to go when you hit it.
If you have developed your game to that point, you’re probably breaking 90 with regularity. You should continue to take lessons, but change your focus radically. You already know how to swing, so you don’t need any swing lessons. What you do need is a lesson on how to hit your fairway wood off the ground. This is a tough shot. Get a lesson on it. You don’t need a chipping lesson, because you can do that, but how about a lesson in chipping from greenside rough? How about a lesson in hitting uphill and downhill putts? See where I’m going with this? You should be learning shots, not swings.
When you play golf, you don’t go out there to swing the club. You’re there to hit the ball toward and into the hole. Most of the time you’re not making a routine play at the ball. You have to make a shot. Once you have the basic skills figured out, the focus of a lesson needs to be doing just that — using the skills you have to hit shots.
On TV, golf looks simple. You know how much harder it is in real life, and how many different kinds of shots you have to play in eighteen holes. Every swing, every stroke at the ball is generally tailored in some way to the shot at hand. The more different shots you can hit, the more you will be able to take whatever the course throws at you. Having a solution for every problem is a comforting way to play golf. It’s knowing how to hit shots that gives you a good score, not knowing how to swing the club.
You might have one shot you want to work on, which you can have your pro teach you at the range. Even better is to have a playing lesson where you go out on the course, drop a ball at a particular spot, and say to the pro, what shot should I hit from here, and show me how to hit it. You can cover five or six shots that way and it will be the most valuable lesson you ever had.
I say again, after you get to a certain skill level, don’t learn swings, learn shots. Becoming a shot-maker is how you get better from there.
