"We all know people…who are at loggerheads with existence; unhappy people who never get what they want; are baffled, complaining, who stand at an uncomfortable angle when they see everything askew. There are others again who, though they appear perfectly content, seem to have lost all touch with reality. They lavish all their affections upon little dogs and old china. They take interest in nothing but the vicissitudes of their own health and the ups and downs of social snobbery. There are, however, others who strike us, why precisely it would be difficult to say, as being by nature or circumstances in a position where they can use their faculties to the full upon things that are of importance. They are not necessarily happy or successful, but there is a zest in their presence, an interest in their doings. They seem to be alive all over."
