Win Friends & Influence People

Dale Carnegie's 1936 textbook on human relations, distilled into a checklist for any high-stakes interpersonal moment. Four parts, thirty principles, all verbatim from the book (sources.md lists every citation).

Core principle

"When dealing with people, let us remember we are not dealing with creatures of logic. We are dealing with creatures of emotion, creatures bristling with prejudices and motivated by pride and vanity." — Carnegie, Part 1, Ch. 1

Behavior change comes from making the other person want to act, not from logic, force, or correction. Every principle below operationalizes this: route around defensiveness, satisfy the desire to feel important, and let the other person own the outcome.

The single most-cited insight in the book — Carnegie returns to it in every part — is William James's line: "The deepest principle in human nature is the craving to be appreciated." Hold that as the lens for everything that follows.

Part 1 — Fundamental Techniques in Handling People

These are the preconditions. If you violate any of these three, the rest of the principles cannot rescue you.
