as was said above, it wouldn't be something for living.
but if I haven't work to maintain my home and have food, I would do the same: programming. because I like it.
and maybe I'd also sponsor serious musical education and free studios for rehearsals to encourage more talents and high quality music.
and if I was rich like hell, I would do something like that what Soros does. he's an amazing person that supports education all over the world, because education is the key to civilization and prosperity.
