Marcus Aurelius

"Do every act of your life as if it were your last."

"If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it."

"Malice, arrogance, cowardice - these are signs of a weak mind."

"True happiness comes from service, not from dominion."

"The human mind is divine."

"Better to die as a lion than to live as a lamb."

"Whenever you encounter adversity, remember it is your chance to practice virtue."

"You are a little soul carrying around a corpse."

"Never regard a man to be unlucky, if all his misfortunes are justly earned."

"Patience, my friend. Even mountains were worn down by water."

"Fortune falls heavily on those who expect nothing and lightly on those who expect everything."

"Wealth consists not in great possessions but in few wants."

"The mind of the wise man is the citadel of the world."

"Turn obstacles into opportunities."

"You cannot be harmed except by yourself."

"Men seek retreats, yet all the while what they need is within themselves."

"Your life is not determined by your circumstances, but by your thoughts about them."

"A person who despises himself will yet despise others, and will often treat them badly."

"Nowhere is there a retreat more perfect for a man than his own soul."

"Stop pretending you're not a man. Act like one."

"The impediment is the way."

"Chaos is merely order we do not yet understand."

"What stands in the way becomes the way."

"Indifference to petty annoyances is a mark of the wise."

"As if you were now dying, leave aside everything else. Only what is truly important matters."

"Strive not to shine before others, but to possess the virtue within."

"The things you think about determine the quality of your mind."

"Forget everything you know about yourself. That is the only way to grow."

"Your time has a limit. Use it, or lose it."

"To love only what happens, what is sent, what is necessary - this is the wise man's path."
