I edit and read lots of books each year, including this one. As the editor I'm usually just looking at the way the book works together and the type layout and not thinking so much about the content. This book I've found unusual in that it has changed the way I think about working with other people. In particular it's the chapter on credibility that I've found most thought provoking. Now when I present ideas to other people I think ahead about what helps make the idea believable to others and what it is about my own background that will help to emphasise why I'm a credible source of this information. This helps me to communicate my ideas in a different way and improves the outcome of the discussions.
