"There are just two classes of boys who should be permitted to read these fascinating pages. The ambitious boys are in one class; those who are determined to make their lives count. That type of boy will be helped toward finding the best outlet for his services. He will learn of fields of investment for his life work which have brought rich returns to other boys. His vision will be broadened, his objective made higher. The other class of boy who should read this book is that in whom the fires of ambition have not yet been kindled; he who is living on the dead level of life, just "groping to and fro". This type of boy will be inspired to tackle the climbing life when he learns of the handicaps which other boys have overcome and of the great goals they have won." - Summary from the introduction
