“To be without some of the things you want is an indispensable part of happiness.”

“Happiness, as is evident, depends partly upon external circumstances and partly upon oneself.”

“With the wise man, what he has does not cease to be enjoyable because some one else has something else. Envy, in fact, is one form of vice, partly moral, partly intellectual, which consists in seeing things never in themselves but only in their relations”

“To like many people spontaneously and without effort is perhaps the greatest of all sources of personal happiness.”

“Few people can be happy unless they hate some other person, nation, or creed.”

“The secret of happiness is this: let your interest be as wide as possible and let your reactions to the things and persons who interest you be as far as possible friendly rather than hostile. ”

“There is something feeble and a little contemptible about a man who cannot face the perils of life without the help of comfortable myths. Almost inevitably some part of him is aware that they are myths and that he believes them only because they are comforting. But he dare not face this thought! Moreover, since he is aware, however dimly, that his opinions are not rational, he becomes furious when they are disputed.”
