Like what these folks do:
It would be awesome to have the kind of cash that lets you own top end sports cars. It would be more awesome to do what this guys does and take kids with cancer on joy rides in his Lamborghini or any one of his exotic collection. Dream Drives for Kids If you are a car guy, its almost enough to make you wish you had caner.
The random act of millionaire kindness that really got me was this one. Woman Goes To Auction To Watch Her House Be Sold. Good Samaritan Buys It Back For Her. I've written or bought a lot of mortgages. I've also had to be part of foreclosure proceedings. Buying a house just to give it back is freaking awesome.
I know if I was ever crazy rich I'd do some crazy selfish things. I hope that I'd also do some wildly generous things too. Like giving someone their house back, or making Christmas special for someone that had to put their kids gifts on layaway. Good on the kind giving people who do stuff for people they don't know, just because they can.
