Think and Grow Rich sat on my bookshelf for years before I finally cracked it open. I’d heard of it before, like everyone. Friends swore by it. YouTube “gurus” name-dropped it. Podcasts quoted it like scripture. But something about the name always made me hesitate. Was it going to be just another rah-rah self-help book? Did it deliver on the promises it made?
A few weeks ago, I finally decided to find out. Grabbed the paperback—yes, the yellowed, vintage-looking book with 1930s fonts.. and got into it.
Turns out, it’s not a investing 101, nor is it a how-to-run-your-own-business manual. It is, however, one of the most powerful mindsets books I’ve read in years. A no-frills, straightforward psychological playbook on wealth, willpower, and personal mastery.
A lot of it feels very much 2026…
A Book that’s More About Thinking Than Growing Rich
As the title implies, the book isn’t so much about actual riches. The dollar bills and skyscrapers and business cards Hill uses to symbolize success are mostly metaphor. The book is more about a re-framing: life, goals, motivation, even self-worth. Think and Grow Rich compiles what Napoleon Hill learned over 25 years interviewing some of the biggest names in his era—Andrew Carnegie, Henry Ford, Thomas Edison, and dozens more—and boiled it down into what he called 13 principles of success.
The most powerful thing to me wasn’t formulas or techniques (because there really aren’t any) but the sheer importance he places on belief. Faith in yourself, your goals, and in the power of positive thought. The entire book starts with the premise that everything begins with desire. Not generic hopes or interests or inklings. A laser-focused, burning, full-blown desire that monopolizes your attention.
It’s this emphasis on mindset that may sound obvious in an era of Tony Robbins and TikTok, but Hill was one of the first to both coin the language and document it in detail. This wasn’t some book peddling shortcuts. It was long-term thinking, persistence, and self-reinvention on display.
What Changed in Me While Reading It
One thing that surprised me: how much I ended up re-evaluating while reading it. Part of it was more intentional: I actually rewrote my financial goals in more specific detail. “I want to retire early” became “I want to have $10 million net worth by 45.” That kind of specificity, Hill says, is key.
But even beyond the goals, reading Think and Grow Rich had me reflecting on how often I second-guess myself. Hill’s chapters on faith and autosuggestion (literally speaking your goals out loud) seemed foreign at first. Saying “I am becoming a disciplined investor” out loud made me cringe at first.
Until it didn’t.
There’s something powerful about forcing yourself to actually hear your own voice say those things. You start to believe it. You act differently. You make more aligned choices. It’s that seemingly-small identity shift that the book is all about. Aligning your internal sense of self to your external goals.
Some Key Ideas That Stuck With Me
There were a lot of takeaways in Think and Grow Rich, but one of the more unexpectedly-helpful ideas was Hill’s section on persistence. The book distinguishes between shallow “keep-going-ness” and a much deeper kind of obsession and purpose.
Hill shares examples of people who were told “no” hundreds of times before making it and it reminded me how easy we have it to give up today if we don’t see success in 6 months.
Another idea that really stuck with me was “mastermind group”—a community of like-minded people who both challenge and support each other. I realized that even though I often read or listen to books and podcasts solo, I grew the fastest when I actually found people around me who were in the same boat. Ambitious builders, investors, creative thinkers. The right peers who will hold you accountable to your own standard make all the difference.
And yes, Hill’s chapter on “sex transmutation” (rechanneling your sexual energy into creative and productive drive) made me raise an eyebrow. But if you get past the sexist language, the basic concept makes sense: energy is energy. Channel it well, and it will fuel your goals.
Parts That Seemed Dated (and Why That Doesn’t Matter)
Admittedly, parts of Think and Grow Rich are very dated. The writing is clunky and antiquated, and he often tells long, rambling anecdotes about long-dead industrialists. Some of the gender roles are downright sexist, and Hill almost exclusively talks about ambition and wealth as if only men could ever want them.
But here’s the thing: if you approach it like a historical artifact, a document of its time, you can get past it. You just have to be willing to parse and filter the relevant parts out. Hidden beneath the old-timey prose is raw, honest success manual for the long game.
It’s also not a book for anyone looking for immediate tactics. This isn’t a book on budgeting or ETF breakdowns or value vs. growth. Instead, it is a lot deeper: foundational thinking around ownership, clarity, and intention that everything else depends on.
Evidence It Still Works Today
It was a relief to see that many modern-day investors and entrepreneurs count the book as one of their most impactful. Daymond John from Shark Tank, for instance, has said that it’s one of the most influential books he’s ever read. Bob Proctor, who made a multi-million dollar business teaching the language of prosperity, was directly inspired by Hill’s work.
Kristy Shen, author of Quit Like a Millionaire, discusses reading Think and Grow Rich before she and her husband saved over $1 million and retired in their early 30s. Tim Ferriss and Grant Cardone both have mentioned the book as influential in their lives—a reminder that people are still being shaped by this book almost a century after its publication.
Does Think and Grow Rich Still Work in 2026
In many ways, it works even better now.
The world we live in is a world of information overload, distraction, options, noise. And yet most of us still don’t have clarity, conviction, or consistency. Hill’s book is a way of stepping back, re-grounding yourself, and hitting the reset button. Questions like What do you actually want? What are you willing to sacrifice for it? How will you train your thoughts to serve you? are as important as ever before.
I realized again that the strategies and tactics change, but the underlying psychology of success doesn’t. The human need for focus, belief, discipline, and community is as relevant today as it was during the Great Depression.
You don’t need to take everything Hill says at face value, of course. But if you can internalize even a few of his concepts—especially those around defining your goals, repeating them daily, and never quitting—you’ll be leagues ahead of 99% of people stumbling through life.
Final Thoughts: Read it. Re-read it.
Think and Grow Rich isn’t the kind of book you read once and then forget about. It’s a book you keep on the shelf and return to time and again. Each time a new line or idea stands out to you depending on where you are in your own journey. Even if you don’t take on every single principle, just being around the energy of the book—the unbridled ambition, the laser-sharp clarity, the relentless positivity—can light a fire in you too.
If you’re looking to build real wealth—not just financial, but mental and emotional—then Think and Grow Rich deserves a permanent home on your bookshelf.
Rating: 4.5 / 5
One of the most powerful mindset books I’ve ever read. Not a perfect book by any means, but a permanently useful one. Best read slowly, intentionally, and with plans to revisit it often.
