If I had 4 years worth of tuition money I would want to do a lot of things. First of all I would probably take like 6 months to travel. I would go places like the Bahamas, Italy, Paris, etc. Some places I would go with my family and other places I would go with my friends.
Then when I came back I might buy a condo, take a trip to my favorite place, IKEA, and buy furniture and stuff. I would paint it myself with bright colors and lots of light.
Then I would proabably still have a little money left over that I would put in a savings account and I would then probably try to find a job as an Elementary School teacher, both for fun and so I wouldn't run low on money. Plus I don't know what I would do with myself sitting around in my condo all day.
