Dress for the occasion.

I was coaching floor hockey on an Indian Reserve years back. My star center--this kid NEVER lost a faceoff--began to lose when he was up against a certain young lady. I couldn't figure out how this was possible. Every single time he was up against 'Suzie', she won. Always. This went on for about three practices. Finally, I asked 'Bill' to let me faceoff against her.

Took me a split-second to diagnose Bill's problem. I asked my wife to get Suzie to practice wearing a turtleneck t-shirt.

Bill began to win the faceoffs again.
