hmmmm..... being a nerd, save it. finish high school, let the intrest pile up. Go to college, still let the intrest pile up. then use it. Oh yeah, and start my own YouTube video thing by buying a cool laptop and recording gear, then save it.
After Uncle Sam takes his liberal chunk, put enough into an annuity to support me in security for the rest of my life; one for each of my kids (not too much, but enough for security the rest of their life); donate the rest to college funds for scholarships. An education is the best thing you can give anyone.
