criticism is dangerous, because it wounds a person's precious pride, hurt his sense of importace and arouse resentment.

People aren't interested in you. They're interested in themselves

Good leaders are scarce; so I'm following myself.

Always avoid the acute angle.

This is a hurried age we're living in. If you've got anything to say, say it quickly, get to the point and stop, and give the other man a chance to talk.

Talk about your own mistakes before criticizing the other person.

If you want to know how to make people shun you and laugh at you behind your back and even despise you, here is the recipe: Never listen to anyone for long. Talk incessantly about yourself. If you have an idea while the other person is talking, don't wait for him or her to finish: bust right in and interrupt in the middle of a sentence.
