Nursing is a big burnout profession, both because of the work involved and the disrespect of administrators (I have a BSN/RN of recent vintage). As mentioned above, it is rewarding and fulfilling if you like it. If you do bedside, you often only work three days a week - three HARD days of 12 hour shifts, but it can be a nice lifestyle. If you don’t mind working nights, you make a very good living with the shift differential. My own RN recently moved to a specialty clinic where she currently works 9-5 weekdays, no holidays and still gets overtime. Sometimes she misses bedside, but not enough to go back lol.
That said … the nursing major is easier to get out of than get into. If you go in as a nursing major, is there enough at the school to keep you there if you change your major?
