I will say a College Education. Teenagers do not need some egg head professors trying to endocrinate them into their way of thinking and they can read the text books themselves (the whole book also) without any of their help. The books will also be cheaper and they won't have to worry about paying to change courses if their "chosen" courses and/or teachers turn out to be losers. If you are worried about job opportunities then keep the book list you've completely read to give to the person who's interviewing you for your dream job. You can tell them that you won't be hounding them for raises all the time to pay off your school loans and they won't have to worry about your transportation because have a realiable car you now have bought with the money you've saved by educating yourself via books and the ever more informative internet.
