An ignorant person is inclined to blame others for his own misfortune. To blame oneself is proof of progress. But the wise man never has to blame another or himself.
EpictetusAsk yourself, "How are my thoughts, words and deeds affecting my friends, my spouse, my neighbour, my child, my employer, my subordinates, my fellow citizens?"
EpictetusYou 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.'
