These are a few things you must be able to do to call yourself a golfer. How many of them do you KNOW how to do?
Hit an intentional fade
Hit an intentional draw
Hit with the ball below your feet
Hit with the ball above your feet
Hit from an uphill lie
Hit from a downhill lie
Hit the ball higher than normal
Hit the ball lower than normal
Hit the ball 125 yards with your 9-iron, 8-iron, and 7-iron
Hit out of fairway bunker
Hit out of a greenside bunker to a specific distance
Pitch to any distance between 50 and 100 yards
Play a chip that checks quickly, and another than runs, with the same club
There’s more, but this is a good enough start. You can add others on your owns you discover them.
How do you learn to do these things? Well, you don’t learn by trying to figure it out yourself. I have posts on most of them, but the best way is to get a lesson.
Have a pro show you how, and take notes. Then practice.
You want to get to the point where the course cannot give you a problem you don’t already have a solution for.
