“One of the great differences between childhood and manhood is that we come to like our work more than our play. It becomes to us if not the chief pleasure at least the chief interest of our lives, and even when it is not this, an essential condition of our happiness. Few lives produce so little happiness as those that are aimless and unoccupied. Apart from all considerations of right and wrong, one of the first conditions of a happy life is that it should be a full and busy one, directed to the attainment of aims outside ourselves....the first great rule is that we must do something – that life must have a purpose and an aim – that work should be not merely occasional and spasmodic, but steady and continuous. Pleasure is a jewel which will only retain its luster when it is in a setting of work, and a vacant life is one of the worst of pains, though the islands of leisure that stud a crowded, well-occupied life may be among the things to which we look back with the greatest delight.”
