“An unexamined life is not worth living for a human being.”

“He who is not contented with what he has, would not be contented with what he would like to have.”

“Education is the kindling of a flame, not the filling of a vessel.”

“Remember that there is no stability in human affairs; therefore, avoid undue elation in prosperity, or undue depression in adversity.”
