'Supreme Personality: Fun in Living. A Doubt, Fear, and Worry Cure' is a motivational book written by psychotherapist Dr. Delmer Eugene Croft. The running theme of the book is best-described by the following passage: “Life is self-realization. Every birth is divine. We are born anew every morning. My wish is that you may catch the gleam, be freed from limitations and enter upon your boundless possibilities. Your endowments are so rich and rare. There is no other person in the world just like you.”
