“Any fool can criticize, complain, and condemn—and most fools do. But it takes character and self-control to be understanding and forgiving.”

“Criticism is futile because it puts a person on the defensive and usually makes him strive to justify himself. Criticism is dangerous, because it wounds a person's precious pride, hurts his sense of importance, and arouses resentment.”

- Dale Carnegie, How to win friends and influence people.
