point is — then determine if it is really worth fighting for in the bigger picture.
Look for points that have an asymmetry in value. Once you understand the math of a negotiation, look where there may be asymmetry. There are always points where there is a fundamental difference in how each side perceives the value. To be effective in negotiation you need to comprehend the balance of trade on every key point. Basically, look where your currency is worth more. Consider, for example, the purchase of a house. If the eventual price is the most important currency for you, then see where there may be a different lever (a different “currency”) to trade for your desired lower price. Sometimes a seller may care more about the timing or certainty of a closing than the price. Taking out a financial contingency, or letting the close happen on whatever time frame the seller wants, may gain you disproportionate benefit in the price. Remember the bigger context and have the empathy and rationality to think about it from the other side.
