Dr. Kohn explains how getting upset on the golf course as a result of a bad shot or a bad break can be very negative, especially if you can't let go and move on. He suggests that understanding what upsets you is of prime importance - maybe you a perfectionist for example. He gives three "coping steps": 1) Let go of the demand and expectations you place upon yourself. 2) Become unglued from the past or from what you cannot change. 3) Mistakes are OK and focus on the positives e.g. being lucky enough to be out golfing with your friends for example. Main instruction is from 0:51 to 4:12 minutes.
