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.
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.
Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth.
You have power over your mind – not outside events. Realize this, and you will find strength.
Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
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?
When another blames you or hates you, or people voice similar criticisms, go to their souls, penetrate inside and see what sort of people they are. You will realize that there is no need to be racked with anxiety that they should hold any particular opinion about you.
What we do now echoes in eternity.
How much more grievous are the consequences of anger than the causes of it.
The first rule is to keep an untroubled spirit. The second is to look things in the face and know them for what they are.
You are a little soul carrying about a corpse, as Epictetus used to say.
Do every act of your life as though it were the very last act of your life.
Perfection of character is this: to live each day as if it were your last, without frenzy, without apathy, without pretence.
Nothing happens to anybody which he is not fitted by nature to bear.
