He who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.
Marcus AureliusAre you distracted by outward cares? Then allow yourself a space of quiet wherein you can add to your knowledge of the Good and learn to curb your restlessness. Nowhere can a man find a quieter or more untroubled retreat than in his own soul. Avail yourself often, then, of this retirement, and so continually renew yourself.
Marcus Aurelius
