The Stoics built their entire mental model around one distinction: what you can control versus what you can't. Weather, news, other people's opinions — all outside your control, so worrying about them is wasted energy. What IS yours: your attitude, your habits, your actions. This isn't passive acceptance — it's ruthless prioritization of mental energy toward the only inputs that actually move your life forward.
