Everyone should have a deep-seated interest or hobby to enrich his mind, add zest to living, and perhaps, depending upon what it is, result in a service to his country.
Dale CarnegieWhen dealing with people, let us remember that we are not dealing with creatures of logic. We are dealing with creatures of emotion, creatures bristling with prejudices and motivated by pride and vanity. ...Any fool can criticize, condemn, and complain - and most fools do. But it takes character and self-control to be understanding and forgiving.
Dale CarnegieThe only way on Earth to influence other people is to talk about what they want and show them how to get it.
