Marcus Aurelius

"Let your scars make you wise, not bitter."

"Success is not final, failure is not fatal: it is the courage to continue that counts."

"The greatest remedy for anger is delay."

"Be like the rock that the waves crash over, unmoved."

"Waste no more time arguing what a good man should be. Be one."

"The impediment to action advances action. What stands in the way becomes the way."

"You have power over your mind—not outside events. Realize this, and you will find strength."

"Confine yourself to the present."

"If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment."

"The universe is change; our life is what our thoughts make it."

"Very little is needed to make a happy life; it is all within yourself, in your way of thinking."

"You could leave life right now. Let that determine what you do and say and think."

"Does what happened keep you from acting with justice, generosity, self-control, sanity, prudence, honesty, humility, straightforwardness, and other qualities that allow a person's nature to fulfill itself?"

"Our life is what our thoughts make it."

"Begin each day by telling yourself: Today I will encounter busybodies, ingrates, egomaniacs, liars, the angry, and cranks."

"A blazing fire makes flame and brightness out of everything that is thrown into it."

"Nowhere can man find a quieter or more untroubled retreat than in his own soul."

"When you arise in the morning, think of what a precious privilege it is to be alive."

"The object of life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane."

"Accept the things to which fate binds you, and love the people with whom fate brings you together, but do so with all your heart."

"Our life is equal to the value we place upon it."

"You have within you right now, everything you need to deal with whatever the world can throw at you."

"Perfectionism is the enemy. Just do the work."

"Be like the rock that the waves keep crashing over. It stands firm and tames the violence of the water around it."

"Forget everything and attack the present problem with fierce focus."

"The best revenge is not to be like your enemy."

"Time is a river of passing events."

"Keep yourself simple, useful, pure, serious, and humble; be a friend to justice; be kind."

"You have been fortunate in life. To be fortunate suggests you must repay it through service."

"Stop whatever you're doing for a moment and ask yourself: Am I afraid of death because I won't be able to do this anymore?"
