I knew a guy with over $200 million networth (owned a chain of businesses in private education around the world, I knew him since I went to one of them).

Really chill guy, you'll never spot him in a crowd. He had a beard, had long hair (kinda Steve Aoki like), wore a button shirt and chino shorts, flip flops, leather bracelet. Drives a camry most of the time. I've seen him squatting in front of an apple store before looking like a hipster.

Bottom line he told us was that he didn't need to flash his wealth, he knew he had way more money than he would ever need in his lifetime and he only spends it to so something he would enjoy or see other people enjoying because that's cool. He invited some of the top students and his staff to celebrate end of school term once with everything like food trucks and performers, and I remember he bought a Ferrari once just to try it out for fun.
