The Law of Success is a book written by Napoleon Hill in 1925. It was originally released as a set of 15 separate booklets before being consolidated into a single-tome book. The Law of Success in 16 Lessons is an edited version of Napoleon Hills first manuscript, which was reworked under the advisement of several contributors. This version was initially published in 1928 as a multi-volume correspondence course. Later editions consolidated the material into a single book.Hill frequently refers to 'The Temple of Success,' and cites the laws and their collective understanding to be the door to the Temple of Success. It is the author's stance that thinking is the most organized form of energy. The 16 lessons include The Law of the Mastermind, A Definite Chief Aim, Self-Confidence, Habit of Saving, Initiative and Leadership, Imagination, Enthusiasm, Self-Control, Doing More than Paid For, A Pleasing Personality, Accurate Thinking, Concentration, Cooperation, Profiting by Failure, Tolerance, and The Golden Rule.
