Marcus Aurelius

“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 criticise?”

“People are not disturbed by things, but by the views they take of them.” 

“Don’t go on discussing what a good person should be. Just be one.”

“Remember that very little is needed to make a happy life."

"I cannot escape death, but at least I can escape the fear of it.” 

Epictetus

"Don't explain your philosophy, embody it."

"Wealth consists not in having great possessions, but in having few wants.” 

"Man is not worried by real problems so much as by his imagined anxieties about real problems.” 

"First say to yourself what you would be; and then do what you have to do.”

"Caretake this moment. Immerse yourself in its particulars. Respond to this person, this challenge, this deed. Quit evasions. Stop giving yourself needless trouble. It is time to really live; to fully inhabit the situation you happen to be in now.”  

Seneca

“We suffer more often in imagination than in reality.”

“Associate with people who are likely to improve you.” 

“Hang on to your youthful enthusiasms – you’ll be able to use them better when you’re older.”

“He suffers more than necessary, who suffers before it is necessary.”
