He who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.
Marcus Aurelius... Allow yourself a space of quiet, wherein you can add to your knowledge of the Good and learn to curb your restlessness. Guard also against another kind of error: the folly of those who weary their days in much business, but lack any aim on which their whole effort, nay, their whole thought, is focused.
Marcus Aurelius
