If you want to be a good conversationalist, be a good listener. To be interesting, be interested.
Dale CarnegieRemember, happiness doesn't depend upon who you are or what you have; it depends solely upon what you think. So start each day by thinking of all the things you have to be thankful for. Your future will depend very largely on the thoughts you think today. So think thoughts of hope and confidence and love and success.
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.
Dale CarnegieYou have it easily in your power to increase the sum total of this world's happiness now. How? By giving a few words of sincere appreciation to someone who is lonely or discouraged. Perhaps you will forget tomorrow the kind words you say today, but the recipient may cherish them over a lifetime.
