A lot of good responses here. When I was going through nursing school, I was stuck too. For the first couple of semesters I wasn't too worried about it. When someone would ask what area I was going to specialize in, I just told them that so far I had enjoyed virtually every area and that I had plenty of time to explore; and I did, until 4th semester came around.
Suddenly I was faced with having to find a job, and I had no idea what I wanted to do!!!!!!!
It seems silly, but I ended up choosing by exclusion. I sat down and made a list of things that I KNEW that I didn't want to do. Not into vomit and feces so much, so no GI lab, or floor for me. Sputum makes me gag every time, so respiratory is not for me, not to mention that vents scare me to death!!! I knew all along that I didnt want to do Peds..... and on and on and on.
Suddenly I reallized that there wasn't a whole lot left. Mainly L and D, oncology and cardiac. I felt that l&D would be too limiting for me as a new grad, I did want to build up some varied basic skills before becoming that specialized. The final decision was made when I spent my senior practicum on a Cardiac Stepdown, working with post cardiac and vascular surguries and heart and lung transplants pre and post op. I loved it, loved it loved it, and ended up working on that floor for a year and a half. Heck, I only left because I wanted to move back home where the cost of living was more affordable. If only I could move that hospital, coworkers and patient population a thousand miles north
Anyway, sorry for rambling. Seriously, when the time comes to make a decision, sit down and make that I DONT wanna list, and you will find that things become much clearer
