How do you know what you want to do?

For the past couple of years, I've been asked the following question: "Do you know what you want to do?" And no, this doesn't refer to when me and my friend are trying to decide what to do on a Friday night (although that does happen often), but more so in the educational context.  I guess I'm at that point in my life where I'm so close to graduating and have to start to seriously think about what I plan on doing next year, five years or even ten years (scary!).  As my year on exchange progresses, I find myself being asked that question more and more often.  And I always have the same answer: "I don't really know.." *nervous laugh*"

But it's time, isn't it?  What do I want to do?

Some of my friends are already graduated and working - as in working in real grown-up type of jobs.  With sixteen consecutive years of school under my belt, my natural instinct kicks in - I don't feel ready for that yet, for that responsibility, not being a student anymore.  My life revolves so much around school and my friends at school.  Not taking classes, having (study) parties, and even stressing over the dreaded exams is, to be really honesty, hard to imagine. 

In that case, it's easy, you tell me.  Go for grad school! Get a Masters! Further your education!  It's a rather tempting idea - remain a student for at least two more years, get a nifty M.sc on my diploma...but what for?  Is it a necessary thing, having two extra years of school? Will it really "further my education"?  And to answer that question, I need to find out what kind of career I want.   

I'll very likely end up applying for grad school (mental note to self: check application deadlines!) but need to start coming up with my options: jobs to apply for, internships, and all that fun stuff.  

So I leave with a couple questions for you: how will I be able to find out what I want to do? How did you know? 

Or maybe a sudden revelation will happen while I'm in Scandinavia. Wouldn't that be nice..
