As a Man Thinketh

Published in 1903, As a Man Thinketh is considered among the worlds greatest self-help books. The book is a powerful reminder that all one achieves or ceases to get is due to his thought process, as thoughts alone are most powerful. Thoughts are the key to unlocking the fulfilments in life that one wants or desires.
The book was also described by Allen as 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.
