16th Roman Emperor from 161 to 180 and Stoic philosopher
Marcus Aurelius Antoninus (26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoic philosopher. He was the last of the rulers known as the Five Good Emperors (a term coined some 13 centuries later by Niccolò Machiavelli), and the last emperor of the Pax Romana (27 BC to 180), an age of relative peace and stability for the Roman Empire. He served as Roman consul in 140, 145, and 161.

If you do the job in a principled way, with diligence, energy and patience, if you keep yourself free of distractions, and keep the spirit inside you undamaged, as if you might have to give it back at any moment— If you can embrace this without fear or expectation—can find fulfillment in what you're doing now, as Nature intended, and in superhuman truthfulness (every word, every utterance)—then your life will be happy.
