Persuading people is a lot easier if you look at it as mutually trying to make the best decision--to be persuaded as much as to persuade--instead of some stupid gimmicky power grab. "I felt so powerful because I got someone to agree with me!" Feel powerful when you're right, feel powerful when you're wrong and can admit it, but feeling powerful because someone else thinks you're right is folly.
