The two biggest things that helped me were learning to have a short memory and using gps. The gps is rough on the ego at first but once you get over the fact that you don’t hit it as far as you think it’s a game changer.
I finally invested in a GPS. I'm so glad I did. After leaching off my friends I had to play a round without one. ( the cart units both failed) . I was a complete wreck. Always unsure of what to hit. so I never hit anything. Even if I am still too inconsistent, the GPS really gives me confidence that I'm selecting the correct club. So I just have to focus on executing a swing.
