My favorite nonsexual fantasy!
If we're talking about 50 million after taxes, here is where I'd put the money...
10 million invested in stocks in various companies that make products I like and use.
10 million invested in tax-exempt municipal bonds.
10 million invested in low-cost mutual funds.
10 million invested in one or more businesses where I would spend most of my time trying to build and grow the business/businesses.
5 million in real estate.
5 million in various collectibles (art, guitars, cars, coins, antiques) just for fun!
Any after-tax profits generated by my investments/businesses would be spent on daily living expenses, reinvested in my investments/businesses, and donated to worthy charities (mostly for cancer research and children's hospitals.)
Now all I have to do is pick those winning numbers!
