Quote by Diogenes Laërtius

"The man who is not afraid of the sea will soon be drowned, for he will be going out on a day he shouldn't."

"It is not that the man has failed, but that he aimed at nothing and succeeded."

"Know yourself."

"Worthless people live only to eat and drink; people of worth eat and drink only to live."

"Education opens doors."

"Education opens doors to endless possibilities."

"I ain't got the education you got, bub."

"You can't put a price on history."
