“The world is vast and our own powers are limited. 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. And to demand too much is the surest way of getting even less than is possible. The man who can forget his worries by means of a genuine interest in, say, the Council of Trent, or the life history of stars, will find that, when he returns from his excursion into the impersonal world, he has acquired a poise and calm which enable him to deal with his worries in the best way, and he will in the meantime have experienced a genuine even if temporary happiness.”
– Bertrand Russell
