buy my dad a motor home / pay for his house / pay for a personal trainer
go on a vacation 3 times a year for a week. christmas break, spring break, and summer break.
finish college
maybe buy a really efficient 4x4 SUV like the 2010 Equinox that gets 32mpg. I would still want an even more fuel efficient vehicle though.
Depending on if the 10 million was already taxed, I would put it either in a Roth IRA or a traditional IRA. Atleast I would max out my yearly IRA contributions until I retire, by investing 6 million in low risk / smaller return stocks and ETF's. I would more aggressively invest 2 million dollars. I would get a couple franchise restaurants in the right spots.
Bring a Chik-Fil-A to a place that doesn't have one near by, or a Qdoba / Chipotle. Open up a few of them and hire someone to manage them while I sit back and make bank off them.
Take a lot of investment classes, and invest aggressively daily.
Get a job and work enough to at least get work health care for my family in a job that is low in stress, and in a field that I enjoy.
I would get the job for the income obviously, because who is to say your investments will go well? I feel if I didn't have a job I would just spend my money foolishly.
I think investment in the stock market / precious metals / C.D.'s combined with owning businesses would be the route I take. Maybe even a shipping logistics company, as well as some other ventures....like franchise restaurants in areas that need one.
You could in theory maybe live in 10 million for the rest of your life.
Oh yeah I would retire at like 40 also, sell all my businesses and just play the markets.
