Criticism is futile because it puts a person on the defensive and usually makes them strive to justify themselves. Criticism is dangerous, because it wounds a person’s precious pride, hurts their sense of importance, and arouses resentment.
If you want others to like you, if you want to develop real friendships, if you want to help others at the same time as you help yourself, keep this principle in mind: Become genuinely interested in other people.
The world is so full of people who are grabbing and self-seeking. So the rare individual who unselfishly tries to serve others has an enormous advantage. He has little competition.
