Dr. Richard C. Cabot, formerly professor of clinical medicine at Harvard. In his book What Men Live By, Dr. Cabot says: “As a physician, I have had the happiness of seeing work cure many persons who have suffered from trembling palsy of the soul which results from overmastering doubts, hesitations, vacillation and fear. ... Courage given us by our work is like the self-reliance which Emerson has made for ever glorious.”
