To be more serious, I would use it to get into the college that I want to get into right now, and then travel to the places I really want to travel to, get into the winter olympics in korea/china, become famous, and then live close the sun
the first thing I'd probably do is buy a new car, and eventually a nice apartment, but I think I'd just pack up and start traveling before even bothering with an apartment.
a..
a small loan of a million dollars?
well I'd build a large tower, host a show called "The Celebrity Apprentice" then try to run for president.
but seriously..?
I'd probably invest FIRST then buy what I want. and hey, if I spend too much investing, then the munnys will come back and I can buy more useless stuff. Because that's how the world works.
save half, spend the other half on stuff. I'd like to buy myself and my parents new cars, renovate our current house (don't wanna buy a new house cuz this ones a great size just needs some updating) get fab clothes. after all that I'd expect to have enough money left to take my family on nice vacations for the next several years
