Each nation feels superior to other nations. That breeds patriotism - and wars.

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.

So if you aspire to be a good conversationali st, be an attentive listener. To be interesting, be interested. Ask questions that other persons will enjoy answering. Encourage them to talk about themselves and their accomplishments

Learning is an active process. We learn by doing.. Only knowledge that is used sticks in your mind.

People do things for "their" reasons, not ours. So find their reasons.

Praise is like sunlight to the warm human spirit; we cannot flower and grow without it. And yet, while most of us are only too ready to apply to others the cold wind of criticism, we are somehow reluctant to give our fellow the warm sunshine of praise.

By criticizing, we do not make lasting changes and often incur resentment.
