If you are distressed by something, it is due to your own estimate of it; and you have the power to change it at will.

This is the chief thing: be not perturbed, for all things are according to the nature of the universal.

The universal nature out of the universal substance, as if it were wax, now molds a horse, and when it has broken this up, it uses the material for a tree, then for a man, then for something else.

From Alexander the Platonic, not frequently nor without necessity to say to any one, or to write in a letter, that I have no leisure; nor continually to excuse the neglect of duties required by our relation to those with whom we live, by alleging urgent occupations.

Change your attitude to the things that bother you and you will be aware of them.

There is but one thing of real value - to cultivate truth and justice, and to live without anger in the midst of lying and unjust men.

Though you break your heart, men will go on as before.
