" a victory of diplomacy did not come when everyone got what they wanted—that made everyone assume they’d gotten the better of her, which encouraged more extravagant demands. The trick is not to satisfy everyone, but to leave everyone feeling they reached the best possible result. They must be satisfied enough to do as you wish, yet dissatisfied enough to know that you bested them. "

― Robert Jordan , Towers of Midnight (The Wheel of Time, #13)
