I'm a Film-Maker.... just wrapping up a position as editor and post-production supervisor on my first feature film project. very gratifying, but SHITLOADS of hard work (14hrs a day, 7 days a week, for months and months on end) I've been on this one for a year.
When you're starting out (like me), the money isn't good, but eventually (or so I hope), the hard work pays off.
my advice: concentrate on having fun and trying different things - you never know you like something 'till you've tried it - sometimes more than once. (like Scotch). Don't worry about your career - when you get to college, don't declare a major until you've taken a few electives and GE classes and have decided what sort of classes you enjoy.
..eventually, you'll probably fall into something you love. (or if what you love is nowhere near anything you can get paid to do, find something you don't hate that you CAN get paid to do - or marry a rich chick)
