“Nothing that goes on in anyone else’s mind can harm you. Nor can the shifts and changes in the world around you. —Then where is harm to be found? In your capacity to see it. Stop doing that and everything will be fine. Let the part of you that makes that judgment keep quiet even if the body it’s attached to is stabbed or burnt, or stinking with pus, or consumed by cancer. Or to put it another way: It needs to realize that what happens to everyone—bad and good alike—is neither good nor bad.”
― Marcus Aurelius, Meditations

“49a. —It’s unfortunate that this has happened. No. It’s fortunate that this has happened and I’ve remained unharmed by it—not shattered by the present or frightened of the future. It could have happened to anyone. But not everyone could have remained unharmed by it. Why treat the one as a misfortune rather than the other as fortunate? Can you really call something a misfortune that doesn’t violate human nature? Or do you think something that’s not against nature’s will can violate it? But you know what its will is. Does what’s happened keep you from acting with justice, generosity, self-control, sanity, prudence, honesty, humility, straightforwardness, and all the other qualities that allow a person’s nature to fulfill itself? So remember this principle when something threatens to cause you pain: the thing itself was no misfortune at all; to endure it and prevail is great good fortune.”
― Marcus Aurelius, Meditations

“Suppose that a god announced that you were going to die tomorrow “or the day after.” Unless you were a complete coward you wouldn’t kick up a fuss about which day it was—what difference could it make? Now recognize that the difference between years from now and tomorrow is just as small.”
― Marcus Aurelius, Meditations
