Do you know someone you would like to change and regulate and improve? Good! That is fine. I am all in favor of it, But why not begin on yourself? From a purely selfish standpoint, that is a lot more profitable than trying to improve others - yes, and a lot less dangerous.

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

The chronic kicker, even the most violent critic, will frequently soften and be subdued in the presence of a patient, sympathetic listener— a listener who will be silent while the irate fault-finder dilates like a king cobra and spews the poison out of his system.

The best things in life are yours, if you can appreciate yourself.

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.

Remember that other people may be totally wrong. But they don't think so. Don't condemn them. Any fool can do that. Try to understand them. Only wise, tolerant, exceptional people even try to do that.

Looking at the other person's point of view and arousing in him an eager want for something is not to be construed as manipulating that person so that he will do something that is only for your benefit and his detriment. Each party should gain from the negotiation.
