How to Win Friends and Influence People Summary: All 30 Principles in 12 Minutes

How to Win Friends and Influence People says that people want to feel important and understood, so if you stop criticising, get genuinely interested in others, remember their names and let them feel the idea is theirs, almost every relationship in your life gets easier.

Dale Carnegie published the book in 1936, in the middle of the Depression, for salesmen and clerks who dealt with people all day and had never been taught how. It has sold more than 30 million copies and is still the book most often handed to a new graduate. The promise is not charm. It is 30 plain principles for handling people, making them like you, changing their minds and leading them without a fight, each backed by a story. The stories are old. The principles are not.

Reading time for this summary: about 12 minutes. The book: 288 pages, about 7 hours.

How to Win Friends in 60 seconds

• Criticism does not work. It puts people on the defensive and makes them justify themselves, so stop criticising, condemning and complaining.
• Everyone wants to feel important. Give honest, specific appreciation, not flattery, and people will do almost anything for you.
• Talk about what the other person wants, not what you want. Arouse an eager want in them.
• Six ways to be liked: be genuinely interested, smile, remember names, listen, talk about their interests, make them feel important.
• You cannot win an argument. Avoid it, admit your mistakes fast, let them talk, and let them feel the idea is theirs.
• To change someone, begin with praise, point out mistakes indirectly, ask questions instead of giving orders, and let them save face.

Who should read it (and who should skip it)

Read it if you have never been taught how to deal with people and you suspect it shows: you argue to win, you forget names, you lead with your own story, or you manage people (children included) by pointing out what they did wrong. The first section alone will change how you talk to your partner, your boss and your six-year-old. It is also the right first book for anyone starting a job that involves customers, patients or students.

Skip it if you have read it once already. The ideas are simple and this summary gives you all 30. Skip it too if you are allergic to American anecdotes about steel barons, insurance salesmen and presidents from a century ago; there are dozens, and the book has no research to offer in their place. And if your real problem is a difficult negotiation rather than everyday relationships, Never Split the Difference is the sharper tool.

Part 1: Fundamental techniques in handling people

Carnegie opens with a gangster. In 1931 "Two Gun" Crowley was caught after a shoot-out in New York, having killed a policeman, and a letter found on him said he had a kind heart that would do nobody any harm. Al Capone considered himself a public benefactor. If hardened criminals do not blame themselves, Carnegie asks, what hope is there that the people you deal with will accept your criticism? That is principle 1: do not criticise, condemn or complain. Criticism puts people on the defensive, wounds pride, arouses resentment, and rarely changes anything. His model is Abraham Lincoln, who after Gettysburg wrote a furious letter to General Meade for letting Lee escape, and then never sent it.

Principle 2 is give honest and sincere appreciation. He quotes Charles Schwab, one of the first people paid a million dollars a year, who put his success down to his ability to arouse enthusiasm by appreciation and encouragement rather than criticism. The deepest urge in human nature, Carnegie says, is the desire to be important, and most of us go home hungry for it. Appreciation is specific and true; flattery is cheap and people can tell. The difference is that one comes from the heart and the other from the teeth.

Principle 3 is arouse in the other person an eager want. His example is Emerson and his son trying to push a calf into a barn and failing, until the maid put a finger in the calf's mouth and let it suck its way inside. Talk about what they want, not what you want.

Try it: For one week, do not criticise, condemn or complain about anyone out loud. Notice how often you want to.

Part 2: Six ways to make people like you

Carnegie's teacher for principle 1, become genuinely interested in other people, is a dog. A dog is the only animal that does not have to work for a living and is loved anyway, because it is simply glad to see you. Theodore Roosevelt stayed up the night before meeting a guest to read up on that person's hobby. You make more friends in two months by being interested in others than in two years trying to make them interested in you.

Principle 2 is smile. Actions speak louder than words, and a smile says "I am glad to see you" before you have said anything; he adds that you can make yourself feel cheerful by acting cheerful. Principle 3 is remember that a person's name is to them the sweetest sound in any language. Jim Farley, who ran Franklin Roosevelt's 1932 campaign, could greet 50,000 people by their first name, and he did it by asking about their family and work and remembering the answers. Andrew Carnegie named a steel mill after a rival to win his business.

Principle 4 is be a good listener and encourage others to talk about themselves. Carnegie spent an evening at a dinner party doing nothing but listening to a botanist, and was later described as a most interesting conversationalist. Principle 5 is talk in terms of the other person's interests; Roosevelt did his homework, and so can you. Principle 6 is make the other person feel important, and do it sincerely. His test is small: tell the post office clerk you admire his hair, and watch his day change.

Try it: In your next conversation, ask three questions before you say anything about yourself.

Part 3: How to win people to your way of thinking

The twelve principles here fall into three groups. The first is about not fighting. Principle 1: the only way to get the best of an argument is to avoid it. Carnegie's student Patrick O'Haire was a truck salesman who won every argument with customers and lost every sale, until he started agreeing with them and letting them talk. Principle 2: show respect for the other person's opinions and never say "you're wrong." Principle 3: if you are wrong, admit it quickly and emphatically; Carnegie, caught walking his dog without a lead, confessed to the policeman before he could be told off, and was let go. Principle 4: begin in a friendly way, as John D. Rockefeller Jr did when he faced striking miners in Colorado with a speech so warm that the strike collapsed.

The second group is about letting the other person do the work. Principle 5: get them saying "yes, yes" immediately, by starting with points you both agree on. Principle 6: let the other person do a great deal of the talking. Principle 7: let them feel the idea is theirs; a sales manager named Adolph Seltz asked his dispirited team what they expected from him, wrote it on the board, then asked what he could expect in return. Principle 8: try honestly to see things from their point of view. Principle 9: be sympathetic with their ideas and desires.

The third group is about motivation. Principle 10: appeal to the nobler motives; people have a real reason and a reason that sounds good, so give them the good one. Principle 11: dramatise your ideas, as a salesman did by throwing coins on the floor to show how much a shop was losing. Principle 12: throw down a challenge. Charles Schwab chalked a "6" on a mill floor at the end of the day shift, the night shift made it a "7", and output rose without a word of criticism.

Try it: Next time you disagree with someone, say "I may be wrong, let us look at the facts" and let them talk first.

Part 4: Be a leader: how to change people without giving offence

The last nine principles are for anyone who has to correct someone and keep the relationship: a manager, a teacher, a parent. Principle 1: begin with praise and honest appreciation. Carnegie's image is the barber who lathers before he shaves, and his example is Calvin Coolidge complimenting a secretary's dress before mentioning her punctuation. Principle 2: call attention to people's mistakes indirectly. When Charles Schwab found workers smoking under a no-smoking sign, he handed each a cigar and said he would appreciate it if they smoked them outside. Principle 3: talk about your own mistakes before criticising the other person, as Carnegie did with his niece Josephine, recalling his own blunders at nineteen before correcting hers.

Principle 4: ask questions instead of giving direct orders. Owen D. Young of General Electric never said "do this"; he said "you might consider this." Principle 5: let the other person save face. When GE needed to move the brilliant but hopeless manager Charles Steinmetz out of his job, they invented a new title for him rather than sack him. Principle 6: praise the slightest improvement and praise every improvement; the example is Stevie Morris, a blind boy praised for his hearing when asked to find a mouse, who grew up to be Stevie Wonder.

Principle 7: give the other person a fine reputation to live up to. Principle 8: use encouragement and make the fault seem easy to correct; a good dance teacher does not list your errors, she tells you that you have natural rhythm. Principle 9: make the other person happy about doing the thing you suggest. Napoleon handed out 15,000 crosses of the Legion of Honour, and when accused of handing out toys he answered that men are ruled by toys.

Try it: Next time you want someone to do something, ask instead of telling, and let them own the plan.

Best quotes from How to Win Friends

• "You can't win an argument." Part 3 in five words.
• "Any fool can criticize, condemn and complain, and most fools do." The case for principle 1.
• "Arouse in the other person an eager want." The whole book's method: start from what they want.
• "Be hearty in your approbation and lavish in your praise." The Schwab line Carnegie built principle 2 on.
• "Let the other person save face." The principle most leaders and parents forget.
• "Give the other person a fine reputation to live up to." Why labels stick, for good and bad.

Where How to Win Friends falls short

The examples are from 1936, and they feel like it. Steel magnates, insurance salesmen, presidents and a gangster or two carry every lesson, there is not a single study in the book, and women appear mostly as wives and secretaries. The advice to smile reads differently to a woman who has been told to smile by strangers her whole life, and Carnegie never considers that the same technique can land as warmth from one person and as a demand from another.

The bigger criticism is manipulation. Many principles ("let them feel the idea is theirs", "get them saying yes, yes", "throw down a challenge") can be run as scripts on people who have not consented to them, and a reader who wants to use them that way will find nothing in the book to stop him. Carnegie's defence, repeated often, is that insincere versions do not work for long, and he is mostly right, but it is a thin ethical fence.

Finally, the book you buy is not the book he wrote. The 1981 revision, overseen by his widow Dorothy Carnegie, cut two whole sections from the original: one on writing letters that get results and one offering seven rules for a happier home life. It also swapped many examples for newer ones and trimmed the dated phrasing. If you want the full 1936 text, you have to look for it.

Carnegie tells you how to be liked and trusted. Covey tells you what to do with the trust once you have it. Voss tells you how to get what you need when the other side does not want you to.

For busy parents: what actually survives real life

Every principle in this book works on a six-year-old and a boss equally. Do not criticise (a child who is told off for spilling learns to hide the spill). Catch them doing something right, and name the exact thing, because "good job" is flattery and "you put your shoes away without being asked" is appreciation. Ask questions instead of giving orders: "what needs to happen before we leave?" gets shoes on faster than "shoes, now." Let them save face in front of their siblings, and give them a reputation to live up to ("you are the one who always remembers the water bottle").

With a partner, the principles that survive are the first three in Part 3: do not argue, admit when you are wrong before you are made to, and begin in a friendly way. A tired evening argument about whose turn it is cannot be won, and Carnegie is honest about that.

The chapter on remembering names is the cheapest social skill you will ever learn, and it is a parent's secret weapon at the school gate: other parents' names, teachers' names, the names of your child's friends.

The weakness is that it can make you sound like a salesman. The fix is to use only the principles you actually feel. A child can tell the difference before you can.
