Your will is absolute, boundless, and unbreakable. Maybe it’s your ideals, maybe it's ambition, or maybe it's just a rock-solid certainty in how you see the world. You are patient beyond belief, even capable of spending countless hours doing mind-numbing tasks. Your willpower is endless and no matter how difficult the situation, even if you're torn in half, locked in a time loop of endless agony for thousands of years, or subjected to a fate worse than death, you'll be able to shrug it off. You will never be left drifting without a sense of purpose, and though you might change your goals and refine your ideals you always have the motivation to fuel turning them into a reality.
This will greatly bolster your sense of self in the face of adversity, and you’ll be able to plant your feet when everyone else is giving up. Of course, you still have emotions and you can still be hurt emotionally, but you'll always be able to maintain your composure and keep your emotions from ruling your decision-making. Take care that you don't become so tunnel-visioned that you fail to see others as actual people with agency.
