If you won the lottery of any amount
I personally would buy a small house in Japan and move there after which I would live simply and retire
And get a Japan citizenship
I don’t believe in buying expensive things it’s a waste of money and it would just cause you to go broke faster
So I would only spend on what I have to
Houses in Japan are pretty cheap but very nice
And start a international food restaurant in Japan
It would just accelerate my plans, but really nothing would change.
I would buy land, build my own house, and continue to work while using the interest on the rest to make my life a little more comfortable.
If it were possible, and feasible, I'd live in total seclusion like the dude from Ex Machina. I'd need Bezos money for that, though.
