The study of truth requires a considerable effort - which is why few are willing to undertake it out of love of knowledge - despite the fact that God has implanted a natural appetite for such knowledge in the minds of men.

"Every role I take is a piece of my soul I leave behind."

【译文】得到恩惠很深时应及早退出身来，春风得意时要及时罢休。千万不要等到是非传入耳内，致使过去的恩爱变成怨仇。
