“Your happiness depends on three things, all of which are within your power: your will, your ideas concerning the events in which you are involved, and the use you make of your ideas.”
― Epictetus, The Art of Living: The Classical Manual on Virtue, Happiness, and Effectiveness

“The greatest obstacle to living is expectancy, which hangs upon tomorrow and loses today. You are arranging what lies in Fortune’s control, and abandoning what lies in yours. What are you looking at? To what goal are you straining? The whole future lies in uncertainty: live immediately.”
― Seneca, On the Shortness of Life

“Remember, it is not enough to be hit or insulted to be harmed, you must believe that you are being harmed. If someone succeeds in provoking you, realize that your mind is complicit in the provocation. Which is why it is essential that we not respond impulsively to impressions; take a moment before reacting, and you will find it easier to maintain control.”
― Epictetus, The Art of Living: The Classical Manual on Virtue, Happiness and Effectiveness
