Principle 1：Don not criticize, condemn or complain.

Instead of condemning people, let us try to understand them. Let us try to figure out why they do what they do.

Criticism is dangerous sometimes, because it might wound a person's pride, hurt his sense of importance,and even arouse resentment.

When dealing with people, we are not dealing with creatures of logic. We are dealing with creatures of emotion.

Principle 2: Give honest and sincere appreciation.

One of the most neglected virtues is appreciation, but it is important in relationship.

Somehow,we neglect to praise our families or friends or fail to encourage them when they have done something good.

Let us try to figure out the other person's good points, and they will cherish your words and treasure them over a lifetime.

Principle 3: Arose in the other person an eager want.

If there is any one secret of success, it lies in the ability to understand the other person's point of view and see things from that person's anger.

Stop telling them what you want, and try to help them realize it's for their benefit.
