A smile is nature's best antidote for discouragement. It brings rest to the weary, sunshine to those who are frowning, and hope to those who are hopeless and defeated. A smile is so valuable that it can't be bought, begged, borrowed, or taken away against your will. You have to be willing to give a smile away before it can do anyone else any good. So if someone is too tired or grumpy to flash you a smile, let him have one of yours anyway. Nobody needs a smile as much as the person who has none to give.
Dale CarnegieSuppose you had inherited the same body and temperament and mind that Al Capone had. Suppose you had had his environment and experiences. You would then be precisely what he was. . . . For it is those things - and only those things - that made him what he was. . . . You deserve very little credit for being what you are - and remember, the people who come to you irritated, bigoted, unreasoning, deserve very little discredit for being what they are.
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 CarnegieIf only the people who worry about their liabilities would think about the riches they do possess, they would stop worrying.
Dale CarnegieI realize now that people are not thinking about you and me or caring what is said about us. They are thinking about themselves-before breakfast, after breakfast, and right on until ten minutes past midnight. They would be a thousand times more concerned about a slight headache of their own than they would about the news of your death or mine.
