Sam, first of all CONGRATULATIONS!!
Most importantly though, follow Shesulsa's advice about your 401K and retirement package. I know you are only 17 (days away from 18!) but take it from an old fart who knows. 17 to 43 seems like about a week. The difference being, i didn't get that advice at your age and if I had to rely on retirement savings from work only I'd have to work until they threw dirt over my grave. Luckily, I have a great job, had some luck, and some brains, so retirement is only a few years away (crosses fingers and knocks on wood) . Don't count on luck coming through no matter how brilliant you are; planning, planning, planning.
