If I had $250B, tbh that's way more money than any individual needs. I'd donate $100B at the very least to charity, and then the next thing I'd do is buy myself a fancy sports car and probably a nice mansion, and maybe a private island. I'd also travel the world (like, literally the world. I'd love to see everything), pay off my family's debts, and then I'd still have a ****ton left over, so I'd probably donate the majority of what's left over after that to charity as well and keep enough so that I wouldn't have to worry about going in debt or anything.
Even if I only had a tiny fraction of that, like 0.01% of that, I'd be set for life and literally never have to work again. I can't even imagine what that kind of life would be like. tbh, I'd probably still work, at least a little bit, because I can't handle not working or at least doing something every day.
