Wonderful insight from a very smart man.

“Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth.”

“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. Our life is what our thoughts make it.”

“If someone is able to show me that what I think or do is not right, I will happily change, for I seek the truth, by which no one was ever truly harmed. It is the person who continues in his self-deception and ignorance who is harmed.”

“Whenever you are about to find fault with someone, ask yourself the following question: What fault of mine most nearly resembles the one I am about to criticize?”

Marcus Aurelius
