hapiness

The secret of happiness is very simply this: let your interests be as wide as possible, and let your reactions to the things and persons that interest you be as far as possible friendly rather than hostile.

The man who acquires easily things for which he feels only a very moderate desire concludes that the attainment of desire does not bring happiness. If he is of a philosophic disposition, he concludes that human life is essentially wretched, since the man who has all he wants is still unhappy. He forgets that to be without some of the things you want is an indispensable part of happiness.

Rules for happiness: something to do, someone to love, something to hope for.
