Another one of those business books where it's a good read if you haven't read any others from the same genre but with the same basically formula where they keep repeating information that can be condensed down into a few pages and which every other business book will tell you but of course they'll rephrase it. If you haven't ever thought much about the influence of the way you talk to people and vice versa I'm sure this can be very eye opening. If you're pretty self aware or have contemplated how difference in you behavior can affect that of others then you're going to just find most of the things in these books to be obvious.
