Work is what we do by the hour. It begins and, if possible, we do it for money. Welding car bodies on an assembly line is work; washing dishes, computing taxes, walking the rounds in a psychiatric ward, picking asparagus–these are work. Labor, on the other hand, sets its own pace. We may get paid for it, but it’s harder to quantify… Writing a poem, raising a child, developing a new calculus, resolving a neurosis, invention in all forms — these are labors.
