I don't usually think about it much. I have big dreams for
  humanities future but for myself I don't dream big, I just do as
  big as I can without overly stressing. Honestly, I don't know.
  Probably use some wisely, some foolishly, hopefully make it last
  'til I die. == BUT, if I was your financial adviser, I'd suggest
  the following: A) Invest using DRiP style on the indexes. (all
  of 'em worldwide but primarily DJIA + s&p) B) Percentage of
  Stocks to bonds: Bond percentage = 100 - your age. Stocks, the
  rest. Simple way to mitigate risk. Bonds seem useless these days
  but they lead to greater stability. Maybe you want revolution,
  in which case, skip the bonds. You _could_ allocate a SMALL
  percentage into Bitcoin style investing but that's just play
  money. Still, has possibilities. Same with "fun stocks" -
  investing in dreams. Just keep it a small percentage of the
  total allocation of paper investment: 5%-10% max. C) Purchase
  run down building and convert to affordable housing. Rent is
  currently not taxable. But... be an ethical slumlord and
  actually fix the stuff that breaks, hire security and what not.
  Oh, and have the managers live at greatly reduced cost. You can
  do co-op or everyone for themselves - or have themes if you
  like, so long as you're not breaking housing laws. D) Start
  several businesses. E) Hire 3 lawyers. (that should be first).
  Gives you multiple perspectives to guide you in uncertain
  waters. Investment percentage? That's up to you. You'll need
  liquid funds as well: I'm tying you up in a lot of
  investments... and you can always draw from them -- but these
  investments SHOULD allow you to live off the profit and not
  touch too much of the initial winnings. = I played around with
  this stuff long ago and learned a lot. I don't do it now, but
  I've checked around, and sound advice now is the same sound
  advice 16 years ago, which is the same sound advice 50 years
  ago. Seems to work. ==
