Does this sound like the set of challenges you might be facing?

• I’m walking into this thing braced for a fight, certain that whatever they get is coming straight out of my pocket
• I’m walking into this dead certain it’s one fixed pie
• Every time I try to weigh whether to keep going, the years and money I’ve already poured in flood right back in and drown out the actual question
• With this one thing, "just a little" never stays little
• In my head the things I’m sure of and the things I’m just guessing at all run together as one blur, so I end up treating my assumptions like hard limits

4. Use "none" when "some" is harder
   A clean zero is often easier to sustain than a tightly rationed "a little."

9. Expand the ZOPA by adding issues to the negotiation
