If some people are so hungry for a feeling of importance that they actually go insane to get it, imagine what miracle you and I can achieve by giving people honest appreciation this side of insanity.
Dale CarnegieIf 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.
Dale CarnegieIt isn't what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about.
