How to Win Friends and Influence People by Dale Carnegieby Parker on TwosPeople who smile tend to manage, teach, and sell more effectively, and raise happier children. There’s far more information in a smile than a frown. That’s why encouragement is a much more effective teaching device than punishment.Your smile comes through in your voice.People rarely succeed at anything unless they have fun doing it.You must have a good time meeting people if you expect them to have a good time meeting you.Everybody in the world is seeking happiness - and there is one sure way to find it. That is by controlling your thoughts. Happiness doesn’t depend on outward conditions. It depends on inner conditions.Act as if you were already happy, and that will tend to make you happy.There is nothing either good or bad but thinking makes it so.Most folks are about as happy as they make up their minds to be.
