I play golf with my son sometimes. He is only twelve. On long summer evenings, when the course is quiet, we wander from tee to green enjoying our time together. As do all talented youngsters, my son expects to play every shot exquisitely, so at some point our enjoyment is usually spoiled because he does not make the perfect swing that he intended or misses a putt that he expected to make. Emotions take over … his shoulders slump, his head goes down, gestures ensue, and inevitably more bad shots follow. Naturally, my mirror neurons notice and, sure enough, I usually emulate him with my own bad shots! Afterward, I explain to my son that everyone hits bad shots, even the great players; he cannot expect to have the game of an expert (yet). He informs me that he can’t stop himself from feeling down. I explain that a body with slumped shoulders and downcast eyes tells its brain to feel down. I tell him that if he walks with his shoulders back and his head held high, his body will tell his brain that all is good with his game.
