The Stoic philosopher who tutored Nero lays down some wisdom on the construction of a full, purposeful existence:

“You must not think a man has lived long because he has white hair and wrinkles: he has not lived long, just existed long. For suppose you should think that a man had had a long voyage who had been caught in a raging storm as he left the harbour, and carried hither and thither and driven round and round in a circle by the rage of opposing winds? He did not have a long voyage, just a long tossing about.”
