And let us be clear: It is not a simple matter of hating your job because it requires you to wake up too early in the morning, or to drag yourself to work when it is too hot or cold or windy or dry or when you are feeling low and want to curl up in bed. It is not a matter of frustration generated when you are called on to do things that are menial or necessary such as emptying garbage cans, sweeping floors, cleaning bathrooms, or in any other manner taking your lowly but well-deserved place at the bottom of the hierarchy of competence—even of seniority.
