Now considered a classic self-help book, As a Man Thinketh's underlying premise is that noble thoughts make a noble person, lowly thoughts make a miserable person. In short: you are what you think. James Allen was convinced that positive thinking produced health, wealth and a sense of well-being. His argument is clear and timeless: within each of us is the spiritual power to overcome the troubles of everyday life. The law of harvest is to reap more than you sow. Sow an act, and you reap a habit. Sow a habit and you reap a character. Sow a character and you reap a destiny.
