Never Split the Difference

The general idea behind Never Split the Difference is that you should view a negotiation as an attempt to get what you want, rather than a compromise where both parties get slightly less than what they want. I believe the best and simplest example of this is the black/brown shoe example shared by Mr. Voss; if your wife wants you to wear black shoes, and you prefer brown, you do not compromise by wearing one of each, because then neither you nor your wife are actually pleased with the result.
