To be without some of the things you want is an indispensable part of happiness.
The secret of happiness is 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.
Man needs, for his happiness, not only the enjoyment of this, or that, but hopes and enterprise and change.
If all our happiness is bound up entirely in our personal circumstances it is difficult not to demand of life more than it has to give.
Contempt for happiness is usually contempt for other people’s happiness, and is an elegant disguise for hatred of the human race.
