Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness. - Bertrand Russell

No rules, however wise, are a substitute for affection and tact.

I have been merely oppressed by the weariness and tedium and vanity of things lately: nothing stirs me, nothing seems worth doing or worth having done: the only thing that I strongly feel worth while would be to murder as many people as possible so as to diminish the amount of consciousness in the world. These times have to be lived through: there is nothing to be done with them.

Envy consists in seeing things never in themselves, but only in their relations. If you desire glory, you may envy Napoleon, but Napoleon envied Caesar, Caesar envied Alexander, and Alexander, I daresay, envied Hercules, who never existed.
