Enthusiasm is the dynamics of your personality. Without it, whatever abilities you may possess lie dormant; and it is safe to say that nearly every man has more latent power than he ever learns to use. You may have knowledge, sound judgment, good reasoning faculties; but no one-not even yourself-will know it until you discover how to put your heart into thought and action.
Dale CarnegieIf 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 CarnegieDon't fuss about trifles. Don't permit little things-the mere termites of life-to ruin your happiness.
