Why prove to a man he is wrong? Is that going to make him like you? Why not let him save face? He didn't ask for your opinion. He didn't want it. Why argue with him? You can't win an argument, because if you lose, you lose it; and if you win it, you lose it. Why? You will feel fine. But what about him? You have made him feel inferior, you hurt his pride, insult his intelligence, his judgment, and his self-respect, and he'll resent your triumph. That will make him strike back, but it will never make him want to change his mind. A man convinced against his will is of the same opinion still.
Dale CarnegieAll the king's horses and all the king's men can't put the past together again. So let's remember: Don't try to saw sawdust.
Dale CarnegieDo the thing you fear to do and keep on doing it... that is the quickest and surest way ever yet discovered to conquer fear.
Dale CarnegieDon't criticize, condemn or complain. Constantly criticizing, condemning and complaining is what breaks most relationships. Instead of criticizing and condemning, figure out how you can solve the problem together. Instead of focusing on blaming the other person for what they did wrong, focus on how you can avoid the problem next time.
