A regrettable paradox of human aspiration is that, because we desire and strive for excellence, we have no time to relish it. Broken things rather than working things demand our attention. Nothing is more pleasant in writing than an inspired sentence that drops full-formed onto the page, but such sentences, by their very effortlessness, only provide a moment's pleasure. A writer's hours are spent bending and hammering the tough, unmalleable sentences that will not take shape. A jeweler delights in a polished stone, but the instant he has chiseled it, he sets it aside and picks up another rough rock. Work is not accidentally unpleasant but essentially so, for we work on what we wish to change, that is, on what we do not like. A company calls long meetings not to discuss strategies that are succeeding but that are failing. Our love of solutions forces us to keep company with problems.
