Think and grow Rich

Think and Grow Rich was written by Napoleon Hill in 1937 and promoted as a personal development and self-improvement book. He claimed to be inspired by a suggestion from business magnate and later-philanthropist Andrew Carnegie. In Think and Grow Rich! he has divided them into 13 principles to be mastered: Desire, Faith, Auto-suggestion, Specialized knowledge, Imagination, Organized planning, Decision, Persistence, the Power of the master mind, the Mystery of sex transmutation, the Subconscious mind, the Brain, and the Sixth sense.
