"That's right. Other than that, it's focus. If you can't beat somebody's diffused will with your own, then you have to go the other way and focus on a single thing as hard as possible, like clinging to a rock in a storm. 'I have to get through this because my beloved mother is waiting for me at home', for example, or 'I can't let myself die until I've had my revenge'. Of course, you're still trying to beat a jōnin, so it's a last resort at best. But if, say, you're so terrified that you're about to slit your own throat, and you have one moment of lucidity in which to try to resist until backup gets there, this is what I'd use."
