Think and Grow Rich Tapa dura - 2015

Think and Grow Rich is an early self-help book by Napoleon Hill, first published in 1937. The book aims to teach readers how to become wealthy by providing practical advice and insights based on Hill's extensive interviews with successful individuals. Through thirteen principles, Hill emphasizes the importance of positive thinking, goal setting, and perseverance in achieving financial success. Hill was considered a leader in the New Thought Movement of the early 19th century. Throughout the decades, Think and Grow Rich has remained a staple of the personal development field; many personalities reference Hill and his ideas, including his use of a 'mastermind group.' The book has sold over 70 million copies. Because the copyright was not renewed (Hill's fourth ex-wife, Rosa Lee Beeland, held the rights), the book is in the public domain, so many editions are available on the market. 

The first edition of "Think and Grow Rich" was published by The Ralston Society in 1937, with an initial print run of 5,000 copies. Signed first editions with the dust jacket are on the market and can be listed for upwards of $20,000, depending on the condition.
