Don'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.
Dale CarnegieYou can't win an argument. You can't because if you lose it, you lose it; and if you win it, you lose it.
Dale CarnegieListen first. Give your opponents a chance to talk. Let them finish. Do not resist, defend or debate. This only raises barriers. Try to build bridges of understanding.
Dale CarnegiePersonally I am very fond of strawberries and cream, but I have found that for some strange reason, fish prefer worms. So when I went fishing, I didn’t think about what I wanted. I thought about what they wanted. I didn't bait the hook with strawberries and cream. Rather, I dangled a worm or grasshopper in front of the fish and said: "Wouldn't you like to have that?" Why not use the same common sense when fishing for people?
