This is a more-than-excellent book. I heard that it comes 2nd most selling book after the Bible. And it certainly deserves that ranking. So far I read this book four times, and I'm loking for the book on tapes so I can listen to it frequently while driving. The book was written in the 1930's, but it is still the best book written on people skills, that can be used at home, at work, with strangers, and everywhere. One of the best investments that can be made.
