Think and Grow Rich
by Napoleon Hill (1937)
Key Takeaways
- ✓ A definite chief aim -- a single, clear, obsessive goal -- is the starting point of all achievement, and most people fail because they never define what they actually want
- ✓ The Mastermind principle states that two or more minds working in harmony create a third, invisible force greater than the sum of its parts
- ✓ Persistence is the distinguishing quality between those who succeed and those who do not -- most people quit just before the breakthrough
- ✓ Auto-suggestion (programming your subconscious through repeated affirmation) is Hill's mechanism for turning desire into action
- ✓ Fear is the primary obstacle to achievement -- Hill identifies six basic fears that paralyze people into inaction
3.5/5
Napoleon Hill distills twenty years of research into the habits and mindsets of America's wealthiest individuals, including Andrew Carnegie, Henry Ford, and Thomas Edison. The book argues that thoughts are things and that a burning desire backed by faith and persistence can achieve any goal...
The Granddaddy of Success Literature
Think and Grow Rich was published in 1937 during the Great Depression and has since sold over 100 million copies. It is one of the most influential books in the self-help and business canon. It is also deeply flawed, historically questionable, and occasionally crosses the line from motivation into magical thinking.
That said, several of Hill’s ideas have proven remarkably durable. The emphasis on clarity of purpose, the power of peer groups (the Mastermind), and the role of persistence in achievement are ideas that show up in nearly every subsequent success book. Hill may not have originated these concepts, but he synthesized them into a framework that millions of people have found useful.
What Holds Up
The Mastermind principle is genuinely valuable. Hill argues that surrounding yourself with a group of people who share your ambition and complement your skills creates a synergistic effect that exceeds what any individual could achieve alone. This insight predates modern research on peer effects and social networks by decades.
The emphasis on persistence is equally timeless. Hill argues that most people who fail do so because they quit too early. The stories he tells — of people who gave up just before discovering gold, metaphorically and literally — drive home the point that discomfort is not the same as failure.
What Does Not Hold Up
Hill’s ideas about auto-suggestion and the transmutation of sexual energy have not aged well. The auto-suggestion framework — essentially, repeating affirmations to your subconscious until they become reality — sits uncomfortably between useful mindset work and pseudoscience. The idea that you can think your way to wealth, taken literally, is harmful advice for people facing structural barriers.
Hill’s research methodology is also suspect. His claimed twenty-year research project with Andrew Carnegie has been questioned by historians. Some of the interviews he claims to have conducted may not have happened.
