Joe,
My swing on the range is fine, but on the course I cannot seem to repeat the good shots I left on the range. This is driving me nuts. What is going on here?
Ronnie

Hello Ronnie,
On the range there is no pressure, no penalty for a bad shot, so your mind is more relaxed. Also you are swinging every few seconds so it is easy to get into a good rhythm. On the course you only swing once every several minutes, and the mind knows there are potential penalties out there on every shot. The mind is a powerful thing. It can change the way you swing without you being aware. Sometimes in the middle of your stroke you could feel a little fear, and when that happens the stroke is usually ruined. You have to train yourself to execute a stroke with certainty, without any fear. If you can commit yourself to that and a bad shot still results, then you can be pretty sure your error was mechanical and you can take steps to correct it. You can already have good mechanics but a sudden fear thought can spoil a swing. If you don’t understand that you might be trying to correct mechanics that had nothing wrong in the first place. These are mental errors that you must be strong to overcome.
