This gave me occasion to observe, that when Men are employ’d they are best contented. For on the Days they work’d they were good-natur’d and chearful; and with the consciousness of having done a good Days work they spent the Evenings jollily; but on the idle Days they were mutinous and quarrelsome, finding fault with their Pork, the Bread, etc. and in continual ill-humour. — Benjamin Franklin
