If you and I want to stir up a resentment tomorrow that may rankle across the decades and endure until death, just let us indulge in a little stinging criticism - no matter how certain we are that it is justified.
Dale CarnegieCriticism of others is futile and if you indulge in it often you should be warned that it can be fatal to your career.
Dale CarnegieThe value of a smile... It costs nothing, but creates much. It enriches those who receive, without impoverishing those who give. It happens in a flash and the memory of it sometimes lasts forever. None are so rich they can get along without it, and none so poor but are richer for its benefits. It creates happiness in the home, fosters good will in a business, and is the countersign of friends.
Dale CarnegieThe ideas I stand for are not mine. I borrowed them from Socrates. I swiped them from Chesterfield. I stole them from Jesus. And I put them in a book. If you don't like their rules, whose would you use?
