From Alexander the Platonic, not frequently nor without necessity to say to any one, or to write in a letter, that I have no leisure; nor continually to excuse the neglect of duties required by our relation to those with whom we live, by alleging urgent occupations.
Marcus AureliusIf you are distressed by something, it is due to your own estimate of it; and you have the power to change it at will.
Marcus AureliusGive your heart to the trade you have learnt, and draw refreshment from it. Let the rest of your days be spent as one who has whole-heartedly committed his all to the gods and is thenceforth no man's master or slave.
Marcus Aurelius
