Query: Worth your time!

This book is worth your time. It will not solve all your problems though. There are some people who are set making a career out of being an A-hole. I got the book on CD's and listened to it about 5 times. The book teaches techniques in listening and speaking that one can use to disarm and reassure those around you. The effects I've experienced with "difficult people" are impressive. Even jerks will be caught off-guard for a while - you may not be able to get through every situation, but it's comforting that you have certainly given it your "best shot". This book shows how.
