Think and Grow Rich by Napoleon Hill

Think and Grow Rich is the blueprint for the success-through-mindset genre, yet investigations found Napoleon Hill fabricated his meetings with Andrew Carnegie and 500 other magnates. With over 100 million copies sold, its unverified anecdotes about "secret" wealth principles lack any empirical backing. This book's 20% fabrication rate is higher than #2's adaptation myth, making it a foundational fraud in self-help literature.
