Turn to the habits of those you live with. They are nearly unbearable, even the most accomplished of them; I hesitate to say it, but a man can scarcely bear even himself. In such darkness and filth, then – in such a constantly changing flow of substance and of time, of motion and things moving – what is worth prizing highly or seriously pursuing, I cannot conceive. Marcus Aurelius, Meditations 5.10.1
