I found this on my dad's shelf and decided to give it a try. I don't typically enjoy books that call their readers "dummies," but I'm willing to overlook that for the sake of learning something useful. The author does a good job of pulling you in at the beginning, and he invites you to skip around to sections that are relevant to what you're trying to accomplish, which I like.
I pulled a bunch of good hints from this book. Since most of my previous jobs involved a metric ass-ton of research and asking the right questions, I was happy to find some ways to "do my homework" more effectively and make sure I was prepared when talking to my interviewees.
Even if you don't have to enter a formal negotiation, this book is great for dealing with the day-to-day "surprises" that befall all of us and have the potential to screw up our lives. Much of it is common sense (keep a cool head, don't raise your voice), but it really helps to have a written reminder.
The author is also really good about using examples, many of which come from classic movies and some of which come from his own experiences. I also appreciated that he provided kind of a script for what to say when things get tough. Of course you're not going to use them word-for-word, but these little dialogues act a great guide to having the right thing to say. Perfect for people like me who feel prone to saying the wrong thing.
Overall, this is a fantastic guide to communicating with just about anyone, and I'm thinking about picking up a copy to keep for myself (once I'm permanently living somewhere, that is!).
