I would use it all for the improvement of third world countrys. I would help get clean water better healthcare and food for the starving. That is what I would spend it on.
I'm dying on the inside and he doesn't seem to care
Hmmmm...I'd probably make sure my immediate family is taken care of, donate to some charities like Celiac, etc, then build a business from investing, and study business. Then just keep rotating that. Oh, I'd also tip well!
First of all I would put 500.000 dollars in the bank and keep them so that my children and future family could live normally and be asured. Then I would spend some money to buy a few things for myself and a few good presents for friends. The rest would probably go for charity.
