I would invest 50% of it in corporate or municipal bonds which currently yield around 10% and would let that earn an easy $50,000 a year for probably the rest of my life.

I would take 10% of it and donate it to charities that further financial education and provide water to drought ravaged countries.

I would put 20% of it in my emergency savings fund and reinvest the remaining 20% back into whatever let me make the first $1,000,000.
buy a cottage for my entire family to enjoy, buy my parents a house and repay their debt, take them to vimy ridge in france (because that's where my mom wants to go)… I would probably also donate alot of money to Alzheimers research because my grandmother died of alzeimers last august. Honestly I would give a majority of my earnings to my parents because they deserve it! But i would obviously treat myself to an insane shopping spree!
Hang on to it like a son of a gun.Don't get married because half could be gone just like that. Saying "I do" could cost you half.You could use it to finance other peoples real estate projects and earn at least 15% interest on your money.Find a good mortgage broker in your area to make loans through.They will find the borrowers for you and also provide proper documentation and protect your interest.All of this costs you nothing.All costs are paid by the borrower.The mortgage broker will handle collections for you and deposit them into your account.Good luck
Invest the $ wisely and conservatively to make sure I'd be ensured a modest living for the 'next' 10 years of my life, and then spend that next 10 years chasing my dream of being a pianist.
buy a nice house , a super speacial awesome car, many electronical gadgets, make a game room in the house(pool arcade and stuff) a bar.
a home gym…
Like most irresponsible people here on Yahoo answers, I would have spent it as soon as I made it, and never accumulated a million dollars. : )
Take a 2 week vacation to an exotic island. Then I would just keep the rest and never worry about paying for food, house, college, etc ever again
pay the mortgage, new car, food, vacation, clothes, new cell phone, etc.
Treat myself to some cool stuff, and treat my parents/friends. Then put some away, and get down to business on expenses. :D
I would buy a 30 ft deep sea fishing boat and go to Mexico and live on the beach is a humble beachhouse and kick back.
Invest most of it, so I have another million in a few years, and use the rest to pay off any debts/mortgages I have.
have it invested for retirement
travel the world first class for 6 months
