I have a college in mind, so I would defiantly pay for that, and put away allot of money for books and food.
I would set my family up with some necessities we currently need, were not the richest people, so we need a couple currently not top priority house repairs.
I would buy a sealed copy of Pokemon Ruby Sapphire and Emerald, and save them as my precious.
I would give lots to charity and fund a couple events to double the amount of money I could give, and maybe start a fund? 1 Million may not be enough for that.
Id put some away for gas money, and basically, not let the money change me too much. Sure id get some things, maybe expensive things, but they are all things I really have wanted for myself since I was young and I would keep them with pride.
