“No one can harm you. ‘If someone succeeds in provoking you,’ Epictetus said, ‘realize that your mind is complicit in the provocation.’ He meant that whatever other people do and say is on them. Whatever your reaction is to what other people do and say—that’s on you. No one can make you angry, only you have that power. Someone can certainly say something offensive or stupid or mean, but no one can make you upset—that’s a choice.”
