How to Win Friends and Influence People

Dale Carnegie didn't initially set out to be an author; he was a YMCA night-class instructor teaching public speaking to business professionals. The book’s content was distilled from a 14-week course he had been refining since 1912. It only reached the page because Leon Shimkin of Simon & Schuster took the course and, after failing to persuade Carnegie to write a book, hired a stenographer to record the lectures.

The marketing of the book was as pragmatic as its content. Shimkin mailed 500 copies to former students as a "refresher," which instantly generated 5,000 more orders. This grassroots momentum pushed it onto the New York Times best-seller list in 1936, where it remained for two years, eventually selling over 30 million copies.

The core philosophy is that human beings are "creatures of emotion" rather than "creatures of logic." Carnegie’s "Twelve Ways to Win People to Your Way of Thinking" emphasizes avoiding arguments entirely and never telling someone they are wrong. By making the other person feel that an idea is theirs, the practitioner bypasses natural defensiveness and social friction.

Success in the Carnegie system relies on specific, actionable habits: remembering names (the "sweetest sound in any language"), smiling, and talking in terms of the other person's interests. The goal is to "arouse in the other person an eager want," aligning your objectives with their internal desires rather than imposing your will through authority.

The original 1936 version was a broader manual for living that included sections on "Letters That Produced Miraculous Results" and "Seven Rules for Making Your Home Life Happier." These chapters offered advice on avoiding domestic nagging and reading books on the "sexual side of marriage"—topics that felt increasingly dated as the decades passed.

In 1981, a revised edition was released to ensure the language and anecdotes remained relevant for a modern business audience. The editors reduced the sections from six to four, excising the marriage and correspondence chapters to focus strictly on the four pillars: fundamental techniques, making people like you, winning people to your thinking, and leadership.

While the book is the seventh most influential in American history according to the Library of Congress, it has faced consistent criticism for its transactional nature. Satirist Sinclair Lewis famously described the method as teaching people to "smile and bob" just to "screw things out of them." Academics have similarly chided the book for encouraging a "lay appeal" that values superficial charm over foundational knowledge.

Carnegie himself defended the work as an "action-book" designed for results. This utility was ironically proven in Nazi Germany, where the book was a massive success despite Carnegie’s philosophy of "butter over guns" being diametrically opposed to official Nazi ideology. The book's popularity often transcends the very cultural or political boundaries it aims to navigate.

The practical power of the Carnegie method is demonstrated by its diverse "alumni." Warren Buffett took the course at age 20 and still displays the diploma in his office today, crediting it with his ability to lead. Similarly, actress Donna Reed attributed her early career success—winning school plays and "Campus Queen" titles—to applying the book’s principles as a teenager.

However, the same techniques for "winning people" have a darker side. Charles Manson used the book’s lessons while in prison to refine his ability to manipulate others into committing crimes on his behalf. This duality reinforces Carnegie’s premise: the tools of human relation are neutral, but their efficacy is potent enough to change the course of a life, for better or worse.
