I started playing pool and golf in the late 50’s. Once you have all the fundamentals down it’s my opinion that both pool and golf are played “between the ears”. Recently a golf professional and I had a conversation about a pre-shot routine that sets up a shot in the “think box” and executes the shot in the “play box”. I applied it to my golf game then started using it playing pool. It’s not a cure all but it sets up a routine that is so much better than getting down over the cue ball and trying to decide what to do.
