“At fifteen my mind was directed to study, and at thirty I knew where to stand.”

“At fifteen I set my heart upon learning. At thirty, I had planted my feet firm upon the ground. At forty, I no longer suffered from perplexities. At fifty, I knew what were the biddings of Heaven. At sixty, I heard them with docile ear. At seventy, I could follow the dictates of my own heart; for what I desired no longer overstepped the boundaries of right.”

“Never tire to study. And to teach to others”

“Study the past if you would define the future.”

“If there were an honorable way to get rich, I’d do it, even if it meant being a stooge standing around with a whip. But there isn’t an honorable way, so I just do what I like.”

“To study and constantly, is this not a pleasure? To have friends come from far away places, is this not a joy? If people do not recognize your worth, but this does not worry you, are you not a true gentleman?”

“Virtue is never left to stand alone. He who has it will have neighbors.”
