Also known as Asset Management.Join a country club with a minimum $500,000 fee, I'm sure you could find a good advisor pretty quickly. That's pretty much what those places are for, really.
How do you become one? Make a butt-load of money, and convince other wealthy people that you know what you're doing enough for them to give you your money, too. Or, get a few degrees and start in the mailroom of one of the big Wall Street firms, something like that.
Oh, sure, ninja-edit on me!
I'd put it in bonds, for the most part, I guess. Decide how much you can set aside to live off the interest - If you're frugal, you could invest $1 million at 5% a year, and live off of that. Then just play with the rest, if you want. Or, invest $10 million at 5% a year, and live off of $500,000. That might be more comfortable. Then, buy toys, start a foundation, help starving artists, whatever you wanna do with the rest.
