Take care not to be Caesarified, or dyed in purple: it happens. So keep yourself simple, good, pure, serious, unpretentious, a friend of justice, god-fearing, kind, full of affection, strong for your proper work. Strive hard to remain the same man that philosophy wished to make you. Revere the gods, look after men. Life is short. The only harvest of existence on earth is a godly habit of mind and social action.
from Meditations, Book 6, 30
