Nick, whatever it is you decide to do just make sure it's something you love.
love fast cars? go to automotive school, get a job and then hobby at the race track, you'll find your way.
love food? culinary school, btw as people eat 3 meals a day your trade will last your lifetime if you desire to work it.
the structure you'll get will be in class studying again, but this time you're studying for a life's career so you'll find the discipline you might have been lacking in the years of your primary education.
make sure you pay for school yourself so the sting of wasting money if you fail will be felt only by you.
of course if you've already got a 'golden radio voice' you might try panhandling, who knows anything can happen.......
