This book has become more pertinent than ever. In a culture in which snark rules, it is good to have a wise and benevolent voice setting forth principles of personal respect and practical courtesy. Although there are a few devices Carnegie suggests using, he also tells the reader to be genuinely interested in other people, to provide honest appreciation, to practice sincere friendliness and also to do tough things like readily admit mistakes. Read the book Carnegie wrote, not the one he is often presumed to have written.
