Nobody is more persuasive than a good listener

My popularity, my happiness and sense of worth depend to no small extent upon my skill in dealing with people.

Even god doesn't propose to judge a man till his last days, why should you and I?

Praise is like sunlight to the warm human spirit; we cannot flower and grow without it. And yet, while most of us are only too ready to apply to others the cold wind of criticism, we are somehow reluctant to give our fellow the warm sunshine of praise.

The only way on Earth to influence other people is to talk about what they want and show them how to get it.

Don't be afraid of enemies who attack you. Be afraid of the friends who flatter you.

Winning friends begins with friendliness.
