" foundational principles—don’t criticize, condemn, or complain; talk about others’ interests; if you’re wrong, admit it; let others save face. Such principles don’t make you a clever conversationalist or a resourceful raconteur. They remind you to consider others’ needs before you speak. They encourage you to address difficult subjects honestly and graciously. They prod you to become a kinder, humbler manager, spouse, colleague, salesperson, and parent. Ultimately, they challenge you to gain influence in others’ lives not through showmanship or manipulation but through a genuine habit of expressing greater respect, empathy, and grace. "
