Getting to Yes with Yourself: And Other Worthy Opponents
Why this book?
I am recommending this book because Ury turns the mirror on negotiators and gets them to look at themselves and why they do what they do at the negotiating table. This is critically important because I believe half our problems in negotiation are with the other party and the other half are within us. Ury gets people to really take this very seriously and to look in a place most ignore.
