The Science of Personal Achievement (Paperback) (ISBN-13: 9781612448046)

This book is based on the findings of elaborate research conducted by Napoleon Hills in the early 1920s, which spanned a twenty-year period and profiled more than 500 successful people. Among them were captains of industry, past presidents, and major economic players in the United States and other parts of the world. His research focused on seeking an understanding of what made these individuals attain outstanding success.
