I wish I read this book a long before I actually did it.
I don't know any person who shouldn't at least glance through this book. We all had such conversation when you have to confront your opponent and in the end you both end up angry at each other without any real progress done as you both feel right and no one wants to listen other person's arguments and no one want to back up.
This book promotes the power of dialogue and its main idea is that in any circumstances you can transform a heated discussion to a pleasant conversation that ends up as a win-win situation. How does it want to do that? That's actually the most interesting part. As it's based on lots of analysis it applies scientific method to human interactions. Honestly, that's the first time when I read a non-technical book that's written in a way that only a pure techie would do. Lots of data, lots of examples and analysis, tables, diagrams you name it and it has it.
One of the best non-technical books I've read so far. Added +5 to my conversation skills.
My score is 5/5
