I'd keep it.
Okay, seriously.
$5 million to my parents so that they could retire.
$3 million for lifestyle changes: New house in a nice area, new car, etc.
$100,000 initially to be spent as guilt-free pleasures: Vacation, new video game systems, taking my friends out to dinner, etc. Actually, more like $2,000; I'm not a spendthrift. But the 100k is there.
EVerything else, let's call it $90 million, gets invested in a very conservative market, say government bonds or CD's. Some of it, MAYbe, if I'm feeling adventurous, gets invested in an index fund. The objective is to give me an income on the interest, so I don't have to touch the principle.
Each year, I'd give myself $200,000 as income to use for the year.
I'd also give myself $50,000 for various charity works--a couple of scholarships.
The rest gets saved.
I could then afford to write full-time, which is my dream. Maybe I could finally get this children's book series finished.
