As a student in Japan, I was introduced to businessmen, to teach English, during their real estate boom. They just so happened to be the children of fathers who had buildings near the Imperial Palace, so became rich (on paper, 100MM+ USD) through no effort. Their lives were about as devoid of happiness that I have ever seen. After partying, hookers, golf, eating at every gourmet place in town, and foreign trips, life became uninspiring and they were a morose bunch to hang out with for dinner and drinks after our language classes. No thanks. A person needs purpose to enjoy life.

You see, that's what I don't get. There are _so_ many things to do that interest me. I will never have enough time to do them.

It's an extension of graduation depression in a way. You have essentially succeeded at the most advertised metric of life, money. If you view life as a linear progression of growing success, then that's the logical conclusion. Good job, you win.
