A thought...
You seem to be at the beginning of your education, as I gather from use of the phrase "when I take up my BS". When I started university, I knew I wanted to do chemistry, but not what type. I figured after 4 years I would take any chemical job out there, figuring, hey, chemistry is chemistry, it is all great. I think I was thinking some sort of organic/drug design type field as I was under the impression that it was paid the best. As undergraduate courses went from general to specific, I found areas I enjoyed (anything synthetic, organic, inorganic, nano, whatever) and others I did not (quantum). I think as you start doing more and more chemistry at higher levels, you will eventually find one area that you will consider a "calling", at this point it is hard to say what area you will end up enjoying most. I found mine, and I enjoy my research on a level bordering on obsessive as a result.
