Whatever you do, and speaking from my own personal experience, pick something that you have a keen interest in!
When I finished high school, I was either going to go to university to do IT or become a chef. I got good enough marks to get into university and picked IT mainly because of its good pay and easy hours. By halfway through the second year, I hated it. Great marks (distinction+) but I had no passion for it. So I dropped out.
I picked up my apprenticeship. After four years of working for very little pay (barely taking home $400 a week) and working 16-20 hours a day six days a week, I qualified. I have now been around the world, worked with some of the best chef's in the world and worked with some amazing people. It may be one of the most stressful jobs you can do (I've had Emergency Room doctors, Paramedics and Soldiers come through and drop out because of the stress and the hours), but I fell in love with food.
I think at the end of the day, find something you are passionate about and can really rally behind otherwise you will end up hating your and your degree. Don't try and convince yourself that you like something either! I'm now 26 and applying to do journalism (UTS,USYD) or business (USYD,UTS,MACQ).
I can either be a food & travel writer or restaurant critic/Michelin Guide Inspector if I get into Journalism, or a product/food researcher for someone like Relais & Chateaux, Simon Johnson or Leading Hotels of the World if I get into business. Find something that can open up the world!
