Dale Carnegie’s best-selling How to Win Friends and Influence People originated from a popular nighttime lecture he used to deliver at the YMCA. The book lists six ways to make people like you: be interested in others, smile, remember a person’s name, be a good listener, talk in terms of the other person’s interests, and make the other person feel important. Novelist Sinclair Lewis summed up Carnegie’s advice: “Smile and bob and pretend to be interested in other people’s hobbies precisely so that you may screw things out of them.”
