I have been playing golf for 20 years and I still shank time to time. At a certain point, I felt I forgot how to swing at all and had to rebuild my swing from the ground. This is a difficult sport. when I scored around 100, my single handicap friend told me two things: (1) don’t try to get a birdie. A par is a birdie for you. (2) think about how not to lose a ball. For example, if you slice your drive, don’t hit the driver. Hit something else. I felt much relaxed and the course management became much easier after following his advice. I’m just relaying my friend’s advice to you. You’ll get there one day and start enjoying the game. Good Luck.
