the power of positive thinking

This is the grandfather of every self-help book on your shelf, and it still reads with surprising force. Peale writes for anyone who feels stuck, tired, or beaten down — the salesman missing quota, the widow in grief, the executive with ulcers. If you want the source code of positive thinking, delivered in plain pastoral prose with concrete exercises, this is it.

1. 1Chapter 1

   Believe in Yourself — on Paper, With Your Assets Listed

   A businessman walks into Peale's study convinced he is finished. He was once a 'two-bit' salesman; he built a real company; now he has lost confidence and calls himself a failure. Peale doesn't console him. He hands him a pen and tells him to list his assets on paper. The man writes, and stares, and realizes something: his abilities are still there. Nothing left but the belief. He rebuilds his confidence, then his business. His secret, he says: 'I get a man and I believe in him. I tell him he can do the job and he does it.'

   The idea

   Peale opens the book with the sentence everything else hangs on: 'Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.' The book's whole purpose is helping you reach a peaceful, happy, successful life through spiritual techniques and a changed mental attitude. He anchors it in William James — 'The greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind' — and in Proverbs: 'as a man thinketh in his heart, so is he.' The surprise is how mechanical his remedy is: write your assets down. Confidence as an exercise, not a mood.

   Try this: Tonight, write a list of your actual assets — skills, experience, relationships — and read it aloud before your hardest task tomorrow.

2. 2Chapter 2

   Drain the Mind, Then Fill It With Peace

   A businessman is drowning. Pressure from every side, and his blood pressure climbing with it. Peale teaches him to empty the mind: consciously visualize draining out every frustration, every fear, every guilt, like pulling a plug. Then fill the emptied space with God's peace, resting on the promise of John 14:27 — 'Peace I leave with you, my peace I give unto you.' The man practices this 'quiet mind' technique daily. His blood pressure drops. His business problems, Peale reports, get solved with 'astonishing rapidity.'

   The idea

   The technique works in two strokes, and the order matters. First subtraction: fear, resentment, guilt get named and drained out, deliberately, like water from a tub. Only then does addition happen — filling the mind with peace instead of leaving a vacuum for the same worries to rush back in. Most people try the second step alone, affirming calm over a mind still packed with sludge. Peale's insistence on emptying first is what makes the practice feel different from whistling past the graveyard.

   Try this: Once today, close your eyes and picture fear and frustration draining out of your mind — then hold one peaceful phrase there for a full minute.

3. 3Chapter 3

   Stop Saying 'I'm So Tired'

   A woman arrives at Peale's study worn down by a complaint that never lifts: she is tired, always tired, day after day. Peale hands her a prescription that sounds almost too simple to take seriously. Stop saying 'I'm so tired.' Every time the words rise, replace them out loud with 'God is my strength, I am full of energy' — and while saying it, picture God's energy flowing into her. She follows the instructions exactly. The fatigue vanishes. She reports a vitality she hasn't felt in years.

   The idea

   Peale treats tired speech as a self-fulfilling sentence. You say you're exhausted, your body hears it, your posture slumps, and the prophecy completes itself. His fix pairs two levers at once: replace the words and add a mental image of energy arriving from outside yourself. Whether the mechanism is divine or psychological, the design is the same — interrupt the verbal habit before it can vote on how you feel.

   Try this: Catch yourself every time you say 'I'm tired' this week and swap it, out loud, for 'God is my strength, I am full of energy.'

4. 4Chapter 4

   Talk to God Like a Neighbor

   A man's business is failing. Out of moves, he sits in a church and prays the plainest prayer imaginable: 'Lord, I have done all I can. Now I leave it in your hands.' Within days, Peale reports, an unexpected solution appears and saves the company. The prayer worked, in Peale's telling, because it was natural — a man talking over his problems with God daily, the way he'd talk to a friend, not reciting formal language.

   The idea

   Peale's prayer power rests on a three-point formula: pray simply; pray believing you will receive; accept God's answer even when it's 'no' or 'wait.' The radical part is the register — conversational, unpolished, the way you'd brief a colleague. Formality, in his view, puts distance between you and the power you're asking to tap. The third point is the one people skip: accepting the answer you get, which is what turns prayer from a vending machine into a relationship.

   Try this: Once this week, pray about your biggest problem in plain spoken words, as if briefing a friend sitting across the table.

5. 5Chapter 5

   Happiness Is a Decision You Make Twice a Day

   A man tells Peale he is unhappy. Peale's answer is blunt: 'you are unhappy because you think unhappy thoughts.' He invokes Lincoln — 'most folks are about as happy as they make up their minds to be' — and tells the man to practice thinking happy thoughts. The man does, and reports back that he has become happy. Peale also tells of a woman whose life felt drab and meaningless; she started 'happiness habits' — smiling deliberately, listing things to be thankful for each morning — and her entire life changed.

   The idea

   The Lincoln quote is the chapter's spine: happiness as a made-up mind, not a lucky circumstance. Peale's two cases show the principle running at two speeds. The man gets the direct instruction — change the thoughts, change the feeling. The woman gets the operational version — small repeated behaviors, a smile on purpose, gratitude listed before the day starts. Both treat happiness as a skill with reps, not a prize the world hands out.

   Try this: Each morning this week, write down three things you're thankful for before checking your phone — then smile, deliberately, even if you don't feel like it.

6. 6Chapter 7

   Expect the Sale Before You Walk In

   A salesman is failing, and Peale finds the cause in his head: he expects rejection before every call. Peale tells him to expect success instead — and to visualize the successful sales calls in advance, seeing them go well before they happen. The man follows through. His sales jump 50% within a month, then reportedly double within a few months, and he starts securing large orders.

   The idea

   Peale states the rule plainly: 'The secret of getting what you want is to expect the best, and to believe that you will get it. This is not mere wishing; it is positive faith.' The distinction is doing real work. Wishing is passive daydreaming; expectation, in his system, is a rehearsal that changes how you carry yourself when the moment comes. The visualization isn't fantasy — it's a dry run that removes the flinch from your voice on the actual call.

   Try this: Before your next intimidating meeting or call, spend two minutes visualizing it going well, start to finish, in specific detail.

7. 7Chapter 8

   'You Have Not Failed Until You Accept Defeat'

   A man's business has collapsed. He is depressed and wants to give up. Peale tells him flatly: 'I don't believe in defeat' — and 'You have not failed until you accept defeat.' He helps the man read his failure as a lesson instead of a verdict. The man starts a new venture with 'no capital but faith,' and rebuilds a successful business. Peale adds a companion case: a man who failed in business three times and finally succeeded, for one reason — he refused to quit.

   The idea

   The chapter draws a hard line between an event and an identity. A business failing is something that happened to you; being a failure is something you agree to. Peale's phrase 'no capital but faith' is doing double duty — the man literally had no money, and the claim is that belief itself functioned as the missing asset. The three-time loser who finally won makes the pattern explicit: persistence isn't one trait among many, it's the trait that converts every other attempt into eventual payoff.

   Try this: Take one project you've quietly written off and write down the single lesson it taught you — then name the next version of it you could start.

8. 8Chapters 8/9

   Ask 'What's the Worst?' and Box the Rest

   Peale describes worry as a habit that can be broken with tools rather than willpower. First tool: interrogation. Ask of any worry, 'What is the worst that can happen?' — then accept that answer. The fear shrinks once it has a defined floor. Second tool: the worry box. Write each worry on a slip of paper, drop it in a box, and set one specific time each week to review them. By the time review day arrives, he claims, most worries have resolved themselves.

   The idea

   Both techniques share one mechanism: worry thrives on vagueness and infinite open loops. Naming the worst case converts a shapeless dread into a bounded problem you can look at. The worry box goes further — it quarantines the worry in time, giving your mind permission to drop it because a scheduled appointment exists to pick it back up. The claimed result, that most worries dissolve before review day, is the point: most of what we rehearse never happens.

   Try this: Start a worry box today: write each worry on a slip, drop it in, and set a 15-minute Sunday review — most will be dead by then.

9. 9Chapters 14/15

   To Have a Friend, Be a Friend

   A lonely man comes to Peale wanting friends. Peale gives him the rule — 'To have a friend, be a friend. Project love, and it will return to you' — and tells him to stop waiting to be liked and start being genuinely interested in other people, accepting them, even praying for them. Within a year, the man has a wide circle of friends. A woman, lonely and friendless, gets the same prescription: deliberately practice being friendly and pray for others. Soon she too has a wide circle.

   The idea

   The rule reverses the usual order of operations. Most lonely people scan rooms asking 'who will like me?' Peale flips the camera: become the one doing the liking, and the liking flows back. Interest, acceptance, and even prayer for others are all forms of projected love — and the return, in both his cases, took months, not days. That timeline matters; it reframes friendship as something you farm, not something you find.

   Try this: Pick three people this week and ask each two questions about their life — then say a silent prayer for each of them by name.

10. 10Chapters 9/10

    The Four-Step Formula for Any Problem

    A man faces a serious personal problem and cannot decide what to do. Peale tells him to get a formula: believe that for every problem there is a solution; pray for guidance; think calmly; act on the best idea that comes. The method includes writing the problem down, praying over it, and then waiting for guidance. The man uses it and reaches a sound decision. Peale reports several others used the same method successfully.

    The idea

    The formula's power is in its sequence. Belief comes first — the conviction that a solution exists — because without it, thinking calmly is impossible; panic forecloses options before you see them. Prayer and stillness create the space where an idea can surface. Then the last step, acting, keeps the whole thing from becoming meditation as procrastination. Write it, pray over it, wait, move. Four steps, in that order, every time.

    Try this: Write your current biggest problem on one page, pray over it tonight, and act tomorrow on the best idea that shows up.

11. 11Chapters 10/11

    Faith as Medicine

    A physician friend tells Peale that many patients aren't really sick — they suffer 'emotional illness,' and that 'Faith in God is the most powerful healing force known to medical science.' A woman with a serious physical ailment that medicine isn't touching begins repeating 'God is healing me now' and visualizing perfect health; her doctors confirm a complete recovery. Peale also tells of a man whose stress-related stomach ulcer healed through faith and relaxation, and a woman with 'incurable' arthritis whose symptoms diminished after she began praying and attending church. He grounds it in James 5:15: 'The prayer of faith shall save the sick.'

    The idea

    Peale isn't dismissing doctors — his cases run through physicians, with Peale and the doctor working together. The claim is narrower and stranger: the mind's faith is a factor medicine can measure but not prescribe. The repeated affirmation and the visualization of health give the body a script different from the one fear has been reading. Whatever you make of the cures, the practice is concrete — words said daily, an image held, worship kept up — not vague hope.

    Try this: If you're battling illness, add one spoken affirmation of health to each morning alongside — not instead of — your doctor's plan.

12. 12Chapter 12

    The Health Formula: Think Health

    Peale lays out a health formula with four moving parts: picture yourself as healthy, affirm health daily, refuse to think sick thoughts, and thank God for your health every day. He compresses it into a marching order — 'Think health. Practice faith. Live by spiritual principles.' The claim underneath: a healthy mind, filled with faith, produces a healthy body.

    The idea

    Notice what the formula bans as much as what it prescribes. 'Refuse to think sick thoughts' is an active veto — every symptom-scanning session, every doom-laden self-diagnosis, gets declined. The gratitude clause is the quiet genius: thanking God for health you don't fully have yet trains attention toward what's working instead of what's failing. The body, in Peale's model, listens to the mind's dominant broadcast and tunes itself accordingly.

    Try this: Each day this week, thank God out loud for your health — and the moment a sick thought starts, refuse it and picture yourself well.

13. 13Chapter 13

    Feed Your Mind New Thoughts Daily

    A defeated man believes he is a 'failure' and a 'nobody.' Peale prescribes a reading discipline: saturate the mind with positive thoughts by reading inspirational literature — the Bible — every day. The man commits to it. Peale reports the result as total: the man's personality and circumstances were completely remade, and he became successful and cheerful.

    The idea

    The word doing the work is 'saturate.' Peale isn't recommending a passing inspirational thought; he's prescribing a daily input that crowds out the old tape looping 'failure' and 'nobody.' Minds, in his view, are like soil — whatever you plant daily determines the harvest. The Bible is his chosen seed because it carries authority for the reader; the mechanism is repetition until the new self-description outvotes the old one.

    Try this: Read one Bible passage or inspirational page every morning this week — same time, same chair, no exceptions.

14. 14Chapter 14

    Relax Your Way to Power

    Peale teaches a relaxation technique with precise steps: sit or lie down quietly, then consciously relax every muscle, starting at the toes and working up to the head. As the body unwinds, repeat a calming phrase — 'I relax, I let go, I am peaceful' or 'The peace of God is filling my mind.' He claims the practice restores energy, lowers blood pressure, and brings mental clarity.

    The idea

    The toes-to-head order is the craft in this technique. Relaxation, done deliberately, is a sweep — muscle by muscle — not a vague decision to chill out. Pairing the physical release with a spoken phrase gives the mind a handhold while the body lets go, so the practice quiets both systems at once. Peale frames the payoff in power terms: this isn't rest for its own sake, it's how you recover the energy and clarity that tension has been eating.

    Try this: Tonight, lie down and relax each muscle from toes to head while silently repeating 'I relax, I let go, I am peaceful.'

15. 15Chapters 12/17

    Draw Upon a Higher Power

    A man is in deep trouble. He has exhausted his own resources — every idea, every contact, every reserve — and comes to Peale with nothing left. Peale teaches him to draw upon 'a higher power' through prayer. Another man faces an impossible business deadline and prays, 'Lord, I need your power' — and experiences a 'surge of energy and ideas,' completing the task successfully. Peale states the principle: 'The secret of a successful life is to draw upon the power of God. This power is available to anyone who will open his mind and heart to receive it.'

    The idea

    The chapter's technique is 'letting go' — releasing a problem to God — and Peale reports people finding relief from tension and anxiety through it. The counterintuitive part is that surrender here isn't passivity. The deadline man prayed and then experienced a surge of energy and ideas; the release preceded the power. Peale's claim is that self-reliance has a ceiling, and the people who hit it are the only ones positioned to discover what's above it.

    Try this: Take the problem you've been white-knuckling and pray, 'Lord, I need your power' — then note what ideas arrive in the next 48 hours.

16. 16Chapters 15/16

    Prescription for Heartache

    A couple's child dies. Grief consumes them. They begin to pray for the strength to accept God's will, and they turn their focus toward helping other grieving parents. Peale reports they found peace and a new purpose. A woman in deep heartache gets the same two-part prescription — pray, and immerse yourself in helping others — and through faith and the passage of time, she finds new meaning in life and her heartache heals.

    The idea

    Both cases share a structure: grief that has no exit through thinking gets an exit through action. Prayer handles the part willpower can't — acceptance of what cannot be undone. Then service redirects the energy of loss toward people still in the fire. Peale doesn't promise speed; 'the passage of time' is part of his medicine. The healing, in his telling, comes from faith plus contribution, not from waiting alone in the pain.

    Try this: If you're carrying grief, pray for strength to accept what can't be changed — then find one person in similar pain and help them this week.

17. 17Chapters 8/9

    Break the Worry Habit With Prayer

    A woman is plagued by anxiety over her son in military service. The worry is constant, and it's eating her. Peale teaches her what he calls prayer therapy — practicing faith and prayer as a deliberate discipline, not an occasional plea. She follows it. Her worries subside, and she gains a peace of mind she hadn't known while her son was away.

    The idea

    What makes this 'therapy' rather than a one-time prayer is the repetition — a practice kept up daily, the way you'd take a prescription. The son's danger hasn't changed; what changed is the mother's relationship to the fear. Peale's claim is that anxiety over things beyond your control is a habit of mind, and prayer is the habit that displaces it. Peace of mind, in this case, didn't come from good news — it came from a new daily routine.

    Try this: If someone you love is in danger or far away, set a fixed daily prayer time for them — and when worry spikes outside that time, defer it to the appointment.

Read this if you're a skeptic who suspects prayer and affirmations are nonsense but keeps lying awake at 3 a.m. rehearsing everything that could go wrong. It's also for anyone whose self-talk has turned into a bully — Peale's techniques are blunt enough to interrupt it, and you can borrow the mechanics even if you skip the theology.
