This edition was bigger than I expected and it's packed full of fascinating content, including real-life examples, diagrams and thought exercises. It's closer to a reference book than your typical self-help fare so will take some time and effort to absorb, but it's worth it for the way it makes you think about how other people see the world.
I was recommended this book a long time ago and had never got round to reading it - I now wish I had taken the time then as I loved it. It is thought provoking but sensible. It has shown me I have work to do but work that is definitely worth doing.
One of the few popular management books that really works. It has some very good points and analogies, which especially work when cooperating with people different from yourself (and can be applied to ones personal life as well).
