Author of such modernist works as “Tropic of Capricorn” and “The Rosy Crucifixion,” Henry Miller was a creative iconoclast in the early 20th century. He broke with many literary traditions in favor of stream-of-consciousness, surrealist, and even mystical writings. Miller’s spirited approach was outlined by the “11 Commandments for Writing” he devised in the 1930s while working on “Tropic of Cancer.” Commandment number three banished anxiety and worry, and Miller gave himself permission to invest fully and passionately in whatever task was before him.
