Thanks to the popularity of The Secret, millions of Americans have been introduced to the wisdom and philosophy of Napoleon Hill, Wallace D. Wattles and Charles F. Haanel. Now, The Secret to Getting Rich Trilogy has combined the three early 20th-Century masterpieces of these revolutionary thinkers so readers can gain a deeper understanding of the trio's proven methods for achieving success. The Secret to Getting Rich Trilogy opens not with the most famous of the three books, Think and Grow Rich, but rather with the less-read Master Key System, the inspiration for the accliamed title. The even earlier pioneering work of Wattles in the areas of "New Thought" and creative visualization is also included for a complete guide to understanding how the laws of concentration, attraction, and harmonious thinking and action can be combined for a powerful system geared toward success.

Napoleon Hill died in 1970. Wallace D. Wattles was a pioneer in the personal growth area having published Science of Getting Rich in 1910, a year before his death in 1911. Charles F. Haanel died in 1949.
