“Here are some of the key lessons from this chapter to remember: ■​A good negotiator prepares, going in, to be ready for possible surprises; a great negotiator aims to use her skills to reveal the surprises she is certain to find. ■​Don’t commit to assumptions; instead, view them as hypotheses and use the negotiation to test them rigorously. ■​People who view negotiation as a battle of arguments become overwhelmed by the voices in their head. Negotiation is not an act of battle; it’s a process of discovery. The goal is to uncover as much information as possible. ■​To quiet the voices in your head, make your sole and all-encompassing focus the other person and what they have to say. ■​Slow. It. Down. Going too fast is one of the mistakes all negotiators are prone to making. If we’re too much in a hurry, people can feel as if they’re not being heard. You risk undermining the rapport and trust you’ve built. ■​Put a smile on your face. When people are in a positive frame of mind, they think more quickly, and are more likely to collaborate and problem-solve (instead of fight and resist). Positivity creates mental agility in both you and your counterpart.”
