When mastery is achieved, dopamine has reached the pinnacle of its aspiration—squeezing every last drop out of an available resource. This is what it’s all about. This is the moment to savor—now, in the present. Mastery is the point at which dopamine bows to H&N. Having done all it can do, dopamine pauses, and allows H&N to have its way with our happiness circuits. Even if it’s only for a short time, dopamine doesn’t fight the feeling of contentment. It approves. The best basking is basking in a job well done.
