As attributed in Marry Your Muse: Making a Lasting Commitment to Your Creativity (1997) by Jan Phillips, p. 176; in recent years this ultimately unsourced attribution has become widespread, but the very earliest such attributions yet found date to the 1990s, it seems to be a slight alteration of a remark long credited to Jean-Baptiste-Camille Corot, since at least 1908
