It has been observed that one's nose is never so happy as when thrust into the affairs of others from which some physiologists have drawn the inference that the nose is devoid of the sense of smell.
Happiness is one pole, sadness is another. Blissfulness is one pole, misery is another. Life consists of both, and life is richer because of both. A life only of blissfulness will have extension, but will not have depth. A life of only sadness will have depth, but will not have extension.
A happy man or woman is a better thing to find than a five-pound note. He or she is a radiating focus of goodwill; and their entrance into a room is as though another candle had been lighted.
