Don't think that all your good hole scores are wasted because the few bad holes you might play. Those good scoring holes show nothing more than how well you can play. The bad holes are (as posted already) showing a lack of, or the wrong focus on your part. I would suggest you learn to play the next shot as well as you can, and forget about your previous shots, no matter if they were bad, or good. My brother for many years was a MLB umpire. When asked what his toughest call was he gave me the common answer among all umpires. "My next one." That same answer still holds true on golf shots and/or putts. GJS
