Excellent book - very insightful. Get's to the root of the problems in your life and then helps you to deal with your reactions to the people and problems in your life. It isn't entirely about succeeding with people although that is ultimately what it is meant to be about - it is a great revelation dealing with all sorts of areas in your life. I can't recommend this book enough. When you read it it seems all so obvious and common sense, and yet, it had never actually occurred to me in the way in which Covey puts it across. This was written in the 70s but is right up to date as the principles never change. Well worth the read.
