1) paying off my parents' mortgage
2) replacing all the faulty equipment my teachers have to deal with because my school gets a crap tonne of funding for athletics (enough to buy three big TVs to put right next to each other outside of the gym) but refuses to spend any of it on academics
3) paying off some family members'/teachers'/etc. student loans
4) donating a bunch of money to my church and other local (and some international) charities, foundations and causes (but not enough that money becomes worthless)
5) giving a bunch of cash to all the homeless people I should ever encounter
6) other misc. good works
7) an iTunes and/or Nintendo spending spree maybe? Not books, though---I buy too many books as it is!
