Marcus Aurelius

“If it is endurable, then endure it. Stop complaining.”
“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.”
“Receive without pride, let go without attachment.”
“How ridiculous and how strange to be surprised at anything which happens in life!”
“Confine yourself to the present.”
“Nowhere can man find a quieter or more untroubled retreat than in his own soul.”
“The art of living is more like wrestling than dancing.”
“Do not act as if you were going to live ten thousand years.”
“Be tolerant with others and strict with yourself.”
“It is not death that a man should fear, but he should fear never beginning to live.”
“The universe is change; our life is what our thoughts make it.”
“A man's worth is no greater than his ambitions.”
“Look well into thyself; there is a source of strength which will always spring up if thou wilt always look.”
“The impediment to action advances action. What stands in the way becomes the way.”
“When you arise in the morning think of what a precious privilege it is to be alive—to breathe, to think, to enjoy, to love.”
“Dwell on the beauty of life. Watch the stars, and see yourself running with them.”
“The soul becomes dyed with the color of its thoughts.”
“If it is not right, do not do it; if it is not true, do not say it.”
“Waste no more time arguing what a good man should be. Be one.”
