I've actually thought about this for an uncomfortable amount of time even before this question was posed. First I would make sure my affairs are in order like a nice house, car and other basic shit. Then I would see to it that my family and close friends are taken care of and never have to work another day in their lives and have a similar living situation to my own.

Now here comes the interesting part. I would likely buy permanent suites in Madison Square Garden and Highmark Stadium. The homes of the New York Knicks and Buffalo Bills respectively. My favorite teams. Then I would shell out money to ESPN if not buy it outright. Simply so I can go onto their shows and complain about whatever grievances I have in sports at that particular time.

Here's what else I would do. I would screw with my friends pretty routinely in good faith light hearted ways, or at least what could be considered such with Bezos money. For example, I would invest money into several engineering companies so that they could create the technology for a real life goblin glider. Then I would dedicate months, possibly years of my life to mastering said goblin glider. Once I have mastered it, I would have broke through their dining room table while they were eating dinner, careful not to harm anyone. Then I would point at them while screaming "FINISH IT!" Then I would foot the bill on whatever damages only to do it again with metal octopus arms six months later or something. I would keep footing them the bill until they politely ask me to stop destroying their house with various Spider-Man based gadgets.

I would donate to charity and do good in the world while taking wonderful vacations and journeys obviously, but I would screw with people most of the time. I mean, I have $201.7 billion dollars. Whatever is in the stock market or bank would grow exponentially so I could do anything for any length of time. Including being a full time troll towards my friends. It's not like I'll have anything better to do once I've solved world hunger.
