At fifteen my mind was directed to study, and at thirty I knew where to stand.
Listen much, keep silent when in doubt, and always take heed of the tongue; thou wilt make few mistakes. See much, beware of pitfalls, and always give heed to thy walk; thou wilt have little to rue. If thy words are seldom wrong, thy deeds leave little to rue, pay will follow.
The gem cannot be polished without friction nor man without trials.
It is better to live in peace than in bitterness and strife
I am not an originator but a transmitter.
Those who do not study are only cattle dressed up in men's clothes.
