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 CarnegieThe very best way in all the world to overcome self-consciousn ess and shyness is to get interested in other people and to think of them and, almost miraculously, your timidity will pass. Do something for other people. Practice deeds of kindness, acts of friendliness, and you'll be surprised to see what happens.
Dale CarnegieYou must have a good time meeting people if you expect them to have a good time meeting you.
Dale CarnegieTell a child, a husband or an employee that he is stupid or dumb at a certain thing, that he has no gift for it, and that he is doing it all wrong and you have destroyed almost every incentive to try to improve. But use the opposite technique, be liberal with encouragement; make the thing seem easy to do, let the other person know that you have faith in his ability to do it, that he has an undeveloped flair for it - and he will practice until the dawn comes in at the window in order to excel.
