I was actually just rereading 'The Once and Future King' last week, and Merlin's whole philosophy on the matter keeps rattling around in my head. He tells young Wart that learning is the only thing that never fails you, that it's the one way to turn a seeming disadvantage into a strength. It's not about breaking a curse with a magic sword, but about outgrowing the definition of the curse itself. The 'jinx' becomes irrelevant because you've built a self that operates on a different plane. Lancelot, in that same universe, is cursed with his own ugly brutality and pride, but his struggle to be gentle, to be a knight for Guenevere, is the overcoming. It's messy and he fails constantly, but the attempt is the character. That feels more real to me than a clean victory. The inspiring part is in the perpetual, grinding effort, not the moment the curse lifts.
You see it in more modern stuff too, like in 'The Fifth Season'. Essun is living in a world literally designed to end her kind, a systemic jinx on an entire people. Her overcoming isn't a triumphant toppling of the Fulcrum; it's her relentless, often furious, preservation of her children and her own identity against a world that wants to erase both. The quotes that get me are the quiet, seething ones about endurance, not the grand speeches. That's the core of it for me—a curse is a constraint, and overcoming it is about finding a way to move within the constraint until you redefine the walls themselves.
