Just out of curiosity, what is your major area of emphasis? Perhaps you just haven't found what it is you really want to do, and therefore you're bored, sick, tired, disgusted?
I can honestly say that I've found my true calling. I'm a music major, working towards a Bachelor of Fine Arts (B.F.A.) Degree in Classical Guitar Performance. Still, I find myself a little sick and tired with the daily routine. However, keeping my long term goals in sight (while also keeping an eye on all short terms goals in between that will get me there) keeps me in perspective, and gives me the drive to keep going.
