Book excerpt: Published around the world, this book has become an undisputed classic in the field of motivational literature. Inspired by Andrew Carnegie, it has been cited by many as the "calling card" that propelled countless numbers to fame and fortune and is the standard against which all other motivational material is measured. Think and Grow Rich and The Think and Grow Rich Action Pack have single-handedly changed the lives of millions of men, women and young adults and produced a legacy of achievement that includes many of today's and yesterday's leaders in business, government and civic organizations. "I knew Napoleon Hill in 1922 when I was a student in Salem College in the town of my birth. Mr. Hill came to our campus as the commencement speaker that year. As I listened to him, I heard something other than the words he spoke. I felt the substance—the wisdom—and the spirit of a man and his philosophy. Mr. Hill said "the most powerful instrument we have in our hand is the power of the mind.' Napoleon Hill compiled this philosophy of American achievement for the benefit of all people. I strongly commend this philosophy to you for achievement and service in your chosen field." —Senator Jennings Randolph, West Virginia
