I agree with Luddite on this one. Definately go to university so that if flying doesn't work out you've got something to fall back on. Perhaps you should even look at doing a non flying based degree so that if you find yourself in the same situation as Luddite, myself and a cast of thousands have been in over the last six months you'll have a chance of getting a proper job if the sh*t hits the fan. You've got the benefit of youth on your side, go have fun while you can.
