Think and Grow Rich by Napoleon Hill

What makes people successful? Why are some people rich and thriving, while others are not? Napoleon Hill devoted twenty-five years of his life to uncover the answer behind this question. He interviewed over 500 affluent men and women, discovering the secrets behind acquiring great wealth and success. He formulated this knowledge into actionable and concise principles that can be applied by anyone.

As relevant now as it was in 1937 when it was first published, his seminal work Think and Grow Rich has helped over 15 million readers identify their goals, believe in their abilities, obtain what they want in life, and join the ranks of top achievers.
