" That I want nothing,” said the Prince, “or that I know not what I want, is the cause of my complaint; if I had any known want, I should have a certain wish; that wish would excite endeavour, and I should not then repine to see the sun move so slowly towards the western mountains, or to lament when the day breaks, and sleep will no longer hide me from myself. "
― Samuel Johnson , The History of Rasselas, Prince of Abissinia
