“Worry: Interest we pay on trouble before it is due.”
Although this appears in Pollard's Connotary in 1932, the aphorism was already in general circulation decades earlier, e.g., it features in an advertisement in The Grape Belt, 2 October 1906, p. 5 http://news.google.com/newspapers?id=LY9CAAAAIBAJ&sjid=tLkMAAAAIBAJ&pg=5967,3394664&dq=worry-is-interest-paid-on-trouble-before-it-falls-due&hl=en. It is also widely misattributed to Dean Inge.
