If you are distressed by anything external the pain is not due to the thing itself but by your own estimate of it, and this you have the power to revoke at any moment
Marcus Aurelius (26 April 121 – 17 March 180 AD) was Emperor of Rome from 161 to 180. Marcus Aurelius was the last of the so-called Five Good Emperors. He was a practitioner of Stoicism, and his untitled writing, commonly known as Meditations, is a significant source of the modern understanding of ancient Stoic philosophy, and is considered by many commentators to be one of the greatest works of philosophy.
