Think and Grow Rich: A Deep Reading of Napoleon Hill's Classic
Napoleon Hill studied five hundred wealthy people for twenty years to find the one principle they shared. This deep reading walks all thirteen steps — desire, faith, autosuggestion, the Master Mind, the sixth sense — and shows how the 1937 classic bridged New Thought and modern manifestation.
Think and Grow Rich (1937) by Napoleon Hill is a success philosophy built from a twenty-year study of more than five hundred wealthy people, distilling the road to riches into thirteen principles around one core idea: a burning, clearly defined desire — impressed on the subconscious mind through faith and autosuggestion — draws to itself the means of its own fulfillment.
Hill said the journey began when Andrew Carnegie challenged him to organize the science of personal achievement. The result was a system, not a pep talk: definiteness of purpose, the Master Mind, persistence, and tapping what Hill called Infinite Intelligence. It is the book that carried New Thought metaphysics into the modern success movement.
Go deeper with The Law of Assumption, the modern method built on the same principle.
Twenty years. Five hundred fortunes. One principle they all shared.
Napoleon Hill claimed to have found the single law behind every great success — and deliberately never wrote it in a single sentence. Here is the whole system, and the secret he left for you to name.
In the late 1920s, a young writer named Napoleon Hill set out to do something no one had attempted: to reduce success itself to a science. By his own account the project was handed to him by Andrew Carnegie, then one of the richest men alive, who hinted at a single principle behind every great fortune and dared Hill to spend twenty years interviewing the achievers of his age to prove it. When Think and Grow Rich appeared in 1937, in the depths of the Great Depression, it offered a country that had lost everything a claim that sounded almost reckless: that wealth begins as a thought, and that anyone willing to discipline their mind could rebuild.
The book has never gone out of print. It has sold in the tens of millions and seeded nearly every success and wealth-mindset teaching that followed. Yet most readers meet it as a list of thirteen principles and miss what it actually is — the hinge in a much longer story, the moment when the metaphysics of nineteenth-century New Thought was rebuilt into a practical, repeatable method for the modern world. To read it closely is to watch an old mystical idea put on a business suit.
Think and Grow Rich: a 1937 book by Napoleon Hill presenting a thirteen-step philosophy of personal achievement, drawn from a claimed twenty-year study of more than five hundred wealthy people.
Definiteness of purpose: Hill's term for a single, exact, time-bound goal that organizes all of a person's energy toward one end.
Infinite Intelligence: his name for the universal creative power the subconscious mind connects to, the same idea earlier writers called Universal Mind or thinking substance.
The secret Hill refused to name
The most famous feature of Think and Grow Rich is a deliberate omission. Hill says a secret runs through every chapter, that it made fortunes for the people he studied, but that he will never state it outright — because a truth a person discovers for themselves works, while one handed over is ignored. He promises you will recognize it when your mind is ready.
Read the whole book and the secret is not really hidden at all. It is the union of three things: a definite purpose held with burning desire, the conviction (faith) that it is already yours, and the disciplined repetition that drives that conviction into the subconscious until it acts on it. The secret means a method of impressing a single goal on the subconscious, not a magic word or formula. Hill simply knew that a reader who assembles the principle themselves will trust it enough to use it.
The thirteen principles of Think and Grow Rich, one by one
Hill organized the road to riches into thirteen steps. They are not independent tips but a sequence: each one prepares the mind for the next, and the system only works when they operate together.
1. Desire
Everything begins with wanting, but ordinary wishing is useless. Hill demands a burning desire so intense it removes any thought of retreat — his image is the warrior who burns his boats so his army cannot consider losing. He makes it concrete with six steps: fix the exact sum you want, decide what you will give in return, set a definite date, form a plan and begin at once, write it all in one statement, and read that statement aloud twice daily while feeling the money already yours. Desire here means a fixed, measurable commitment with a deadline, not a hope.
2. Faith
Faith, for Hill, is not religious belief but a state of mind you manufacture on purpose. It is the confidence that your goal is already achieved, held so steadily that the subconscious accepts it as fact. Faith is the emotion that gives your thoughts the charge they need to reach Infinite Intelligence — without it, the other principles stay inert.
3. Auto-Suggestion
Auto-suggestion is the tool that builds faith: the deliberate, repeated feeding of a chosen thought to the subconscious until it is accepted without argument. This is the mechanical heart of the book. Read your written aim aloud with feeling, often enough, and the subconscious stops distinguishing it from reality and begins organizing your attention and behavior around it.
4. Specialized Knowledge
Information alone enriches no one. Hill separates general knowledge — interesting trivia — from specialized knowledge that is organized and directed at a defined aim. Specialized knowledge is power only when applied. You acquire what your goal requires, or you borrow it by surrounding yourself with people who already have it.
5. Imagination
Imagination is the workshop where the plan is built. Hill distinguishes synthetic imagination, which rearranges existing ideas into new combinations, from creative imagination, the channel through which hunches and inspiration arrive. Desire supplies the goal; imagination gives it a workable shape.
6. Organized Planning
A desire must be crystallized into a practical, written plan and acted on immediately. If the first plan fails, Hill says, replace it with another, and another, until one works — the failure is in quitting, not in planning. This is also where he discusses leadership and the qualities that make a person worth following.
7. Decision
Hill found that successful people reach decisions quickly and change them slowly, while failures decide slowly and reverse course constantly. Procrastination and indecision are the enemies; the habit of deciding firmly, and not being swayed by the opinions of others, is what protects a definite purpose from erosion.
8. Persistence
Persistence is the sustained effort that converts desire into its physical equivalent. Most people quit at the first sign of defeat, when, Hill insists, every setback carries the seed of an equivalent or greater benefit for those who keep going. Persistence is a habit that can be built deliberately by holding the definite aim in front of the mind.
9. The Power of the Master Mind
The principle Hill prized most: the coordination of two or more minds, in a spirit of perfect harmony, toward a definite purpose. He claimed that such an alliance creates a third, intangible force greater than the sum of its members, and that no great fortune was ever built without one. Practically it gives access to others' knowledge, capital, and experience.
10. The Mystery of Sex Transmutation
Stripped of its 1937 framing, this is not really about sex at all. Hill argues that the human creative drive is the most powerful energy a person possesses, and that achievers learn to redirect it away from mere appetite and into the pursuit of their purpose. Transmutation means channeling your strongest energy toward your goal, not suppressing it.
11. The Subconscious Mind
The subconscious is the relay station of the whole system. It receives the emotionalized thoughts you feed it through auto-suggestion and passes them to Infinite Intelligence, then returns plans and answers. Because it works day and night whether you direct it or not, Hill says you must consciously plant positive, definite goals before fear and doubt plant themselves.
12. The Brain
Hill describes the brain as a broadcasting and receiving station for thought. Through the subconscious it sends out the vibration of your dominant ideas and picks up the thoughts of others, especially within a Master Mind. It is his attempt to give the transmission of thought a physical mechanism.
13. The Sixth Sense
The final principle is the apex, available only after the other twelve are mastered. The sixth sense is the faculty of hunches, flashes of inspiration, and inner guidance — the point where Hill's method shades from deliberate technique into something closer to intuition, the direct line to Infinite Intelligence.
The closing step: clearing the six ghosts of fear
Before any principle can work, Hill says, the mind must be swept clear of the six basic fears — the fear of poverty, of criticism, of ill health, of lost love, of old age, and of death. These fears are states of mind, and because they are states of mind they can be controlled and replaced by decision. Indecision, doubt, and fear are the trinity he tells the reader to defeat first.
— The Core Claim —
Whatever the mind of man can conceive and believe, it can achieve.
Napoleon Hill, the line that condenses the entire bookDesire: the starting point of all achievement
Hill opens not with money but with wanting. Ordinary wishing is useless, he argues; what creates is a desire so intense that it crowds out every alternative. His emblem is Edwin Barnes, who wanted to be Thomas Edison's business partner so badly that he arrived with no money, no introduction, and no fallback, and simply refused to be anything else until it happened. Hill's instruction is to burn the bridges — to leave yourself no line of retreat, the way a general who burns his boats guarantees his army will not consider losing.
He makes this concrete with six steps: fix the exact sum you desire, decide what you will give in return, set a definite date, form a plan and begin at once, write it all in one statement, and read that statement aloud twice daily while feeling the money already in your possession. Desire here means a fixed, measurable commitment with a deadline, not a vague hope. This insistence on a precise, emotionalized image is the same demand Wallace Wattles made a generation earlier; you can trace that older root in Wallace Wattles' Science of Getting Rich, which Hill's method quietly systematizes.
Faith and autosuggestion: how the goal gets in
Faith, in Hill's hands, is not religious belief but a state of mind you manufacture on purpose. The tool for manufacturing it is autosuggestion: the repeated, deliberate feeding of a thought to the subconscious until it is accepted as fact. Say your written aim aloud, with feeling, often enough and the subconscious stops distinguishing it from reality and begins organizing your behavior, your alertness, and your decisions around it.
This is the mechanical heart of the book, and it is pure mental science. Faith means a conviction engineered through repetition, not a feeling you wait to arrive. The premise — that the subconscious accepts a clearly impressed idea and externalizes it — is precisely the law that Thomas Troward's Edinburgh Lectures had spelled out philosophically three decades before Hill turned it into a daily drill.
Hill called it autosuggestion. The modern practice calls it assumption. The Law of Assumption gives you the exact daily technique.
Get the BookKnowledge, imagination, and the plan
Hill is blunt that information alone makes no one rich. Knowledge is only potential power; it becomes real power when it is specialized, organized, and directed at a defined aim. He separates general knowledge (interesting trivia) from specialized knowledge (organized for action), and tells the reader to acquire or borrow whatever specialized knowledge their goal requires — often by surrounding themselves with people who already have it.
Imagination is the workshop where the plan is built. Hill distinguishes synthetic imagination, which rearranges old ideas into new combinations, from creative imagination, the channel through which hunches and Infinite Intelligence speak. The plan that imagination produces must then be put through organized planning, decisive decision-making, and relentless persistence. Imagination here means the deliberate shaping of plans, not idle daydreaming. Hill notes that most failures come from indecision and the habit of quitting at the first defeat, when the seed of an equivalent success usually sits inside that very setback.
The Master Mind: the principle Hill prized most
If there is a crown jewel among the thirteen, Hill believed it was the Master Mind: the coordination of two or more minds, in a spirit of perfect harmony, toward a definite purpose. He claimed that when minds align this way a third intangible force emerges, greater than the sum of its parts, and that no one had ever accumulated a great fortune without it. Carnegie, he said, attributed his entire steel empire to such an alliance.
There is both a practical and a mystical layer here. Practically, a Master Mind gives you access to others' knowledge, capital, and experience. Mystically, Hill believed the group's combined mental energy tunes each member into a stronger current of Infinite Intelligence. The Master Mind means an active alliance built for a shared goal, not casual networking or a circle of supporters.
— The Master Mind —
No two minds ever come together without thereby creating a third, invisible force which may be likened to a third mind — and Hill believed great fortunes are built there.
A paraphrase of Hill's central principle of organized powerTransmuting energy, and the deeper faculties
The chapter modern readers find strangest is the transmutation of sexual energy. Stripped of its 1937 framing, the idea is straightforward and not really about sex at all: the human creative drive is the most powerful energy a person has, and the achiever learns to redirect it away from mere appetite and into the pursuit of their definite purpose. Transmutation means redirecting your strongest creative drive toward your goal, not suppressing or denying it.
The closing principles turn inward. The subconscious mind is the relay station that takes your emotionalized thoughts and passes them to Infinite Intelligence. The brain, in Hill's metaphor, is a broadcasting and receiving station for thought vibration. And the sixth sense — the faculty of hunches and inspired ideas — is what becomes available once the other twelve principles have been mastered, the point where the system shades from method into something closer to intuition.
The six ghosts of fear
Hill ends the book where most self-help refuses to look: at what stops people. Before any of the principles can work, he says, you must clear the mind of the six basic fears — the fear of poverty, of criticism, of ill health, of lost love, of old age, and of death. These fears, usually operating below awareness, are states of mind, and because they are states of mind they can be controlled and replaced by decision. Indecision, doubt, and fear are the trinity he tells the reader to defeat first.
Common misconceptions about Think and Grow Rich
Misconception: the book says you can think yourself rich without working. Hill devotes whole chapters to organized planning, decisive action, specialized knowledge, and persistence. Thought sets the aim; disciplined action delivers it.
Misconception: the Carnegie origin story is documented fact. Biographers have questioned how much of Hill's account is literally true, including whether the famous Carnegie commission happened as described. The principles, however, stand on their own as a system readers have tested for almost a century, and that honest distinction is worth keeping.
Misconception: it is the same as positive thinking. Positive thinking is a mood. Hill's system is a structured discipline — definiteness of purpose, written goals, autosuggestion, a Master Mind, and persistence against fear.
Misconception: the sex transmutation chapter is about abstinence. It is about channeling creative energy into productive work, not denying it.
Where Think and Grow Rich sits in the lineage
The reason this book matters more than its rivals admit is its position in history. Behind Hill stands a tradition: the New Thought writers who argued that mind is the creative cause of circumstance. Wattles gave that tradition a wealth-focused method in 1910; Troward gave it a philosophy in 1904. Hill took the same metaphysics, stripped the explicit mysticism, dressed it in the language of Carnegie and Edison and American enterprise, and made it sound like business strategy. That repackaging is exactly why it reached millions who would never have picked up a metaphysical text.
From Hill the line runs forward to the modern manifestation teachers. The torch passes to figures like Neville Goddard, who took Hill's autosuggestion and Troward's subconscious law and refined them into the precise daily practice of assuming the feeling of the wish fulfilled. Read in sequence, the three books are one continuous argument across a century.
— The Universe Unveiled Reading —
At The Universe Unveiled, Think and Grow Rich is read as the bridge text: the work that carried New Thought metaphysics out of the mystical and into the mainstream, translated the law of the subconscious into a step-by-step success method, and handed the torch to Neville Goddard's Law of Assumption.
