The Stoic distinction between what's up to us and what isn't (eph' hēmin / ouk eph' hēmin) is sharper than most modern adaptations preserve. Epictetus restricts the 'up-to-us' category to *judgments, intentions, desires*. Not your reputation, not your body, not your career. That's narrower than 'control what you can' suggests. The discipline is in noticing how often you treat external outcomes as if they were yours to control.
