“The happy man is not he whom the crowd deems happy, namely, he into whose coffers mighty sums have flowed, but he whose possessions are all in his soul, who is upright and exalted, who spurns inconsistency, who sees no man with whom he wishes to change places, who rates men only at their value as men, who takes Nature for his teacher, conforming to her laws and living as she commands, whom no violence can deprive of his possessions, who turns evil into good, is unerring in judgment, unshaken, unafraid, who may be moved by force but never moved to distraction, whom Fortune when she hurls at him with all her might the deadliest missile in her armory, may graze, though rarely, but never wound.”

-Seneca the Younger
