As a Man Thinketh is a self-help book which deals with the power of thought, and the use and application of thought to create happiness. The book shows how each person holds the key to every condition, good or bad, that enters into their life, and that, by working patiently and intelligently upon their thoughts, a person can remake their life, and transform their circumstances.

As a Man Thinketh eventually became read around the world and brought Allen posthumous fame as one of the pioneering figures of modern inspirational thought. Also included are four of Allen's other self-help books, including From Poverty to Power, Eight Pillars of Prosperity, The Mastery of Destiny, and Out from the Heart. Alan's books continue to be a source of inspiration to motivational and self-help authors around the world.
