"Extreme busyness, whether at school or college, kirk or market, is a symptom of deficient vitality; and a faculty for idleness implies a catholic appetite and a strong sense of personal identity. There is a sort of dead-alive, hackneyed people about, who are scarcely conscious of living except in the exercise of some conventional occupation. Bring these fellows into the country, or set them aboard ship, and you will see how they pine for their desk or their study. They have no curiosity; they cannot give themselves over to random provocations; they do not take pleasure in the exercise of their faculties for its own sake; and unless Necessity lays about them with a stick, they will even stand still. It is no good speaking to such folk: they cannot be idle, their nature is not generous enough; and they pass those hours in a sort of coma, which are not dedicated to furious moiling in the gold-mill. When they do not require to go to the office, when they are not hungry and have no mind to drink, the whole breathing world is a blank to them. If they have to wait an hour or so for a train, they fall into a stupid trance with their eyes open" (Robert Louis Stevenson - An Apology for Idlers & Other Essays; tradução em português; segue para aqui)
