Men are disturbed not by the things that happen, but by their opinion of the things that happen.

There is nothing good or evil save in the will.

When you are offended at any man's fault, turn to yourself and study your own failings. Then you will forget your anger.

If a person had delivered up your body to some passer-by, you would certainly be angry. And do you feel no shame in delivering up your own mind to any reviler, to be disconcerted and confounded?

If someone speaks badly of you, do not defend yourself against the accusations, but reply; "you obviously don't know about my other vices, otherwise you would have mentioned these as well

It’s time to stop being vague. If you wish to be an extraordinary person, if you wish to be wise, then you should explicitly identify the kind of person you aspire to become.

When something happens, the only thing in your power is your attitude toward it. It is not the things that disturb us, but our interpretation of their significance. Things and people are not what we wish them to be nor are they what they seem to be. They are what they are.
