Michael Josephson: The beginning of positive thinking

  I am a strong believer in the power of positive thinking, which is the title of a best-selling book published in 1952 by Dr. Norman Vincent Peale, a controversial preacher and pastor who popularized the idea that if you can change your attitude, you can change your life. He urged people to consciously train themselves to be optimistic and enthusiastic, to believe in themselves, to refuse to dwell on negative thoughts, and to visualize success. He also vigorously advocated forgiveness, gratitude, and building one’s own character.
