As a Man Thinketh by James Allen. In this classic book on thinking, the book describes how each of us shapes the events around us, creating our own lives in abundance.As himself Allen describes, "It shows how, in his own thought-world, each man holds the key to every condition, good or bad, that enters into his life, and that, by working patiently and intelligently upon his thoughts, he may remake his life, and transform his circumstances. ...and it can be carried in the pocket."
