“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

“No one could endure lasting adversity if it continued to have the same force as when it first hit us. We are all tied to Fortune, some by a loose and golden chain, and others by a tight one of baser metal: but what does it matter? We are all held in the same captivity, and those who have bound others are themselves in bonds - unless you think perhaps that the left-hand chain is lighter. One man is bound by high office, another by wealth; good birth weighs down some, and a humble origin others; some bow under the rule of other men and some under their own; some are restricted to one place by exile, others by priesthoods: all life is a servitude.

So you have to get used to your circumstances, complain about them as little as possible, and grasp whatever advantage they have to offer: no condition is so bitter that a stable mind cannot find some consolation in it.”
― Seneca, On the Shortness of Life: Life Is Long if You Know How to Use It

“People are frugal in guarding their personal property; but as soon as it comes to squandering time they are most wasteful of the one thing in which it is right to be stingy.”
― Seneca, On the Shortness of Life

“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
