The difficulty is, all swing thoughts decay, like radium. What burned up the course on Wednesday has turned to lead on Sunday. Yet it does not do to have a blank mind: The terrible hugeness of the course will rush into the vacuum, and the ball will spray like a thing berserk. A swing thought is the golfer’s equivalent of the rock climber’s Don’t look down. With it, we reduce the huge circumambient room for error to a manageable somatic circumference. The score, the stakes, the beer in the clubhouse should all be ousted by some swing thought — which is a swing thought in itself.
