When you are right, let’s try to win people gently and tactfully to our way of thinking, and when we are wrong—and that will be surprisingly often, if we are honest with ourselves—let’s admit our mistakes quickly and with enthusiasm. Not only will that technique produce astonishing results; but, believe it or not, it is a lot more fun, under the circumstances, than trying to defend oneself.
Remember the old proverb: “By fighting you never get enough, but by yielding you get more than you expected.”
Principle 3: If you are wrong, admit it quickly and emphatically.
~ Dale Carnegie, How to Win Friends and Influence People, (1936)
