"Paradoxically, I have found peace because I have always been dissatisfied. My moments of depression and despair turn out to be renewals, new beginnings. If I were once to settle down and be satisfied with the surface of life, with its divisions and its cliches, it would be time to call in the undertaker... So, then, this dissatisfaction which sometimes used to worry me and has certainly, I know, worried others, has helped me in fact to move freely and even gaily with the stream of life."
