From President Donald Trump, Trump 101 by Donald Trump, 2006:
I believe that the key to striking a deal is persuasion, not power. Persuasion is diplomacy at its best-the ability to convince people to accept your ideas. You don’t want to force people to accept your ideas. That’s a recipe for disaster. Instead, you want them to think that the decision was theirs, which gives them a greater sense of power and control. Your objectives should be to make your adversaries feel like they’re your partners, not your victims. Present your ideas in a way that will not intimidate your adversaries or make them feel that they are being forced to surrender. In successful negotiations, all parties should feel satisfied with the outcome.
