STYLETHREAD -- LET'S TALK SHOP!

I say just concentrate on getting a degree.  Any degree.  To be honest, I don't think it matters much.  Just graduate from college first, then work on figuring out what you want to do, unless you want to be in a specialized field that requires a specific major (like you want to be a doctor).

Then enter the workforce and start figuring it out.  It's much easier and much less expensive to change jobs than it is to change majors, so I would worry about the degree first and what you want to do with the rest of your life second. 

You're only 23 and to be expected to know what you want to do until you retire is asking a bit much.  I think if you ask most of us on this board what it is we want to do with our lives, you'd probably find that most of us have switched around in the past or are looking to switch around in the future. 

I know it's hard to focus when you don't have a definite end goal in sight, but you just have to do it.  Instead of trying to focus on "what you want to be when you grow up" start looking at smaller goals.  Finish the next exam.  Then enroll in classes for next semester.  Then you study and you focus on the next exams.  Do that until you're done.  But you definitely don't need to worry about what it is you want to do with the rest of your life right now.

Hope this helps.  Also, FWIW, I'll bet you ever single person on this board has been where you're at right now--feeling confused, lost, and unsure of what you want to do next.  Just try not to sweat it and don't let those feelings get you off track.
