I'd give most of it away or start some kind of foundation. Having that much money, amongst all the poverty here in South Africa, it would just feel immoral.

The money I'd spend on myself would be to own an average middle class home, a normal car, and maybe a project car if I could get some utility from it. And on paying off medical debt and spending it on medical treatments to minimise my chronic back pain. And to set up a fund that pays me enough every month so I never have to worry about hunger or not having enough money by the end of the month to do stuff.
