The real power here isn't the claim to control—it's Henley's insistence on mastery *despite* circumstance, written while he was losing his foot to disease. He's not saying life won't deal you a terrible hand; he's saying the one thing no circumstance can steal is your response to it. When you face a genuine setback (a failed exam, a rejection, a diagnosis), the temptation is to believe you've lost agency entirely, but Henley reminds us that agency lives in the smaller, harder choice: how you carry yourself through what you cannot change. That distinction between what happens to you and what you do with what happens—that's where actual freedom lives.
