Here he argues that the power of thought and positive self-esteem is the only true measure of a person's greatness. As Wattles himself says: "This book is for the men and women, young or old, who wish to make the most of life by making the most of themselves. "I have tried to show plainly, simply, and without unnecessary words, the way to power and capability; I know that the system herein set forth will work; it cannot fail.
