Usually I don't like books of this sort because I find them simplistic. Admittedly this book is written for a general audience, but the author still makes an effort (and succeeds, in my opinion) in distinguishing between people who fit in to one of his types and people who can be difficult at times, but don't quite fit in a specific category. I never had the feeling of "oh, that could be anyone." And the techniques he gave to deal with difficult people were concise and easy to use. He really focuses on the fact that we can't change others, we can only change how we chose to respond, which is vital. A very positive, encouraging, readable book. I've already noticed a difference in my relationships after only a few weeks.
