Epictetus

If anyone tells you that a certain person speaks ill of you, do not make excuses about what is said of you but answer, "He was ignorant of my other faults, else he would not have mentioned these alone.

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

Don't explain your philosophy. Embody it.

There is only one way to happiness and that is to cease worrying about things which are beyond the power or our will.

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

If you want to improve, be content to be thought foolish and stupid.

The key is to keep company only with people who uplift you, whose presence calls forth your best.

It's not what happens to you, but how you react to it that matters.

He who laughs at himself never runs out of things to laugh at.

Other people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.
