1920. A book of inspiration for young men. This work is written by 160 men of achievement. These men tell the secrets of their accomplishments in these pages, not reckoning the value of their literally golden moments, over their own signatures, and such is a secret no longer. They have uncovered this hidden treasure of their lives. They have made the philosopher’s secret known, and our young readers may walk on their beaten paths up the hill, laboriously, perhaps, but confident that the best things are worth going after.
