How do I stay motivated when doing my job perfectly means no one notices?

You officiate at the highest level and can read a game in a heartbeat, and the strange reward for excellence is invisibility: do it perfectly and no one knows you were there. To be noticed only when you err is a hard bargain. Your weariness with it is understandable. But turn it over. Your goal was never to be seen; it was to let the game be about the players, not you. When you vanish into a clean match, you have not failed to be noticed, you have succeeded at your true purpose. The invisibility is the trophy, oddly shaped as it is. Since the crowd will not cheer a call gone right, you must be the one who keeps the score of your own excellence. You know when you read it perfectly. Let that private certainty feed you. The finest officials, like the finest of anything quiet, are content to be the reason the thing ran well, whether or not a single soul thanks them for it.
