" But even after we’ve just caught the winning pass in the Superbowl, there’s always tomorrow and tomorrow and tomorrow. If our life is a good one, a life of mastery, most of it will be spent on the plateau. If not, a large part of it may well be spent in restless, distracted, ultimately self-destructive attempts to escape the plateau. The question remains: Where in our upbringing, our schooling, our career are we explicitly taught to value, to enjoy, even to love the plateau, the long stretch of diligent effort with no seeming progress?
