「And remember that if you abide in the same principles, these men who first ridiculed will afterwards admire you; but if you shall have been overpowered by them, you will bring on yourself double ridicule.」
「Remember that it is not he who reviles you or strikes you, who insults you, but it is your opinion about these things as being insulting. When then a man irritates you, you must know that it is your own opinion which has irritated you.」
