The Secret of Achievement is one of Marden's earliest works, written four years after the incredible success of Pushing to the Front. Courage, Self Control, Good Habits, Decision and Tenacity, are some of the traits of a person that Marden analyzes in this book, which are what he calls the "secrets" to get ahead in life. The author dedicated his life to gather the messages engraved in the wisdom of the ages, and to transfer them into dozens of volumes and thousands of pages, each and every one a true gem of the ages.—Print ed.
