Hmm, this sounds like a nice diversionary game.
Pay off mortgage and car lease, etc. ($100k)
Renovate my home so it sucks less ($20k)
Give some money to those in my family who wouldn't blow it retardedly ($50k)
Take about $100k to live off of, and use as startup capital for some of my business ideas, which I would focus on for the next 1-2 years.
Invest the rest in a split between growth oriented mutual funds, dividend ETFs, commercial bonds, and my own personal stock picking.
I don't really believe in donating large sums of money to charities. I give a little here and there, but I've always assumed it's smarter for me to build up my retirement fund, which I'll only live off the interest of, and then when I die, part of that will be setup to donate for perpetuity.
I also wouldn't give a huge chunk of my money to family right away, since I have more faith in my investing and business skills, to make more money, so that I would be better able to help my family with those funds.
