"The world turns aside to let any man pass who knows where he is going."

"If anyone tells you that a certain person speaks ill of you, do not make excuses about what is said of you but answer, 'He was ignorant of my other faults, else he would not have mentioned these alone…"

"Control your perceptions. Direct your actions properly. Accept what is outside your control. Willingly do what needs to be done."

"It is impossible for a man to begin to learn what he thinks he already knows."

"When you are offended at any man's fault, turn to yourself and study your own failings."
