The BATNA acronym helps people understand negotiating a bit better, but outside of education, I don't see that it has much use.
That's what 99.9% of all negotiation advice I ever saw boils down to. Basically beat the game before it beats you.
Really cute... until you remember most people don't live to "play the negotiation game". They want a stable paycheck and to raise their family.
But who's asking, right.
