Don't Argue

In business (and at home, too) as well as politics the person you defeat in an argument today may be the person whose cooperation you need tomorrow. Arguments make people stake out positions and defend them. And the more you try to prove them wrong, the harder they will resist you. People may feel overwhelmed and stop arguing with you. But that doesn't mean you've won them over. Most of the time, when you win an argument, you lose an ally.
