As a Man Thinketh is a self-help book by James Allen, published in 1903. It was described by Allen as "Specifically dealing with the power of thought, and particularly with the use and application of thought to achieve the outcomes you want. I have tried to make the book simple, so that all can easily grasp and follow its teaching, and put into practice the methods which it advises. It shows how, in his own thought-world, 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, they may remake their life, and transform their circumstances.

"A book that will help you to help yourself", "A pocket companion for thoughtful people", and "A book on the power and right application of thought."
