Hopefully people in your general field or with a similar experience may give you an idea of what particular jobs you can go for. My personal advise is not to go to Uni unless you DO know what you want to do.
My school put so much emphasis on Uni that they made it seem like it was a choice between Uni and homelessness. They funneled everyone into applying to Uni's even if they expressly stated that they would decline all offers. Maybe take a year of working after you finish school. Get yourself a nice bit of money while you spend the year exploring different career options. In this time, you could even contact people in fields that interest you for advice. By the end, you'll have a better understanding of what you want to spend your tuition on and the money to back up your decision wherever you decide to go.
Good luck!
