I agree with JustBeachy - it's got to be a personal decision.
I think the negatives about nursing are articulated more commonly than the positives. The negatives often are the first things that come to mind. There are positives, but sometimes it's hard to remind ourselves to see the positives. I hated being a floor nurse (loved some of the patients but hated having 6 patients all night every night). I love my current job (I work in the OR).
Job market - depends on what part of the country you live in. Often it helps to work part time in an organization during nursing school
as many places want to hire from within.
Fulfillment - also depends on where you live/who you work for. My current employer is way better to RNs than my previous employers. It can also depend on coworkers on a given unit...
Family time - nursing is pretty flexible. Most jobs have per diem/as needed staff, part time (12-32 hours a week generally) and full time (36-40 hours a week) options. That said, one shift a week on nights would be a pain in my book and I wouldn't do it - trying to sleep before and after work? Not cool.
By the way - it is also easier to vent to other nurses, especially those familiar with your specialty, than to talk to family members about the pitfalls of work. It's why a lot of us complain online about work... Not that families don't listen, but they can't fully or truly understand something they don't have experience with.
