Dale Carnegie
The father of modern interpersonal skills who transformed millions of lives through the art of human communication
Dale Carnegie (1888-1955) was the founder of modern interpersonal skills training. Born into poverty on a Missouri farm, he achieved success through self-education and speech training, opening his first interpersonal skills and public speaking course in New York in 1912. How to Win Friends and Influence People, published in 1936, has sold over 30 million copies and remained on bestseller lists for decades. Carnegie's core insight was that success in human relations depends on genuine interest in others, not manipulative techniques; on giving sincere appreciation before any criticism; and on always seeing things from the other person's perspective. The Dale Carnegie Training organization he founded still operates in more than 80 countries worldwide.

Beliefs and mental models
- Belief 1 - The underlying logic of people skills is not manipulation technique, but sincerity. Only by genuinely caring about others can you win true friendship and influence. Feigned enthusiasm is worse than indifference, because people can sense its inauthenticity.
- Belief 2 - Criticism is dangerous because it wounds pride and arouses resentment. People cannot be changed through criticism; they only change when they feel understood and respected. Even when someone is clearly wrong, direct criticism only makes them more defensive.
- Belief 3 - Remembering and frequently using someone's name is the simplest way to make them feel valued and respected. Being recognized is one of humanity's deepest psychological needs, and a person's name is the central symbol of their identity.
