Epictetus said this quote
“ You know yourself what you are worth in your own eyes; and at what price you will sell yourself. For men sell themselves at various prices. This is why, when Florus was deliberating whether he should appear at Nero's shows, taking part in the performance himself, Agrippinus replied, 'Appear by all means.' And when Florus inquired, 'But why do not you appear?' he answered, 'Because I do not even consider the question.' For the man who has once stooped to consider such questions, and to reckon up the value of external things, is not far from forgetting what manner of man he is. ”
