《史记·七十列传·季布栾布列传》
他一定是自负有才能，这才蒙受屈辱而不以为羞耻，以期发挥他未曾施展的才干，所以终于成了汉朝的名将。
彼必自负其材，故受辱而不羞，欲有所用其未足也，故终为汉名将。
He must have been self-conceited and thought he had talent, that's why he bore the humiliation but didn't feel ashamed, in order to display his unused talent, so he finally became a famous general of the Han Dynasty.
