Such is the state of life, that none are happy but by the anticipation of change: the change itself is nothing; when we have made it, the next wish is to change again. The world is not yet exhausted; let me see something tomorrow which I never saw before.
Samuel Johnson (1709-1784) English writer, lexicographer, critic
The History of Rasselas, Prince of Abissinia, ch. 47 (1759)
