Well I'll have to admit that I don't love being a nurse. I'll have to say though that during this economic downturn I've been thankful that I haven't had to worry about work and I actually have been able to keep a full time and prn job.
I don't think the money is as good as people make it out to be. You can make killer bucks if you work every weekend night shift, but who wants to do that? I've always had a M-F, 7-4 type of schedule, first in the OR and now as a school nurse. My pay is not nearly what it should be after 9 years of nursing, and a BSN but I don't have to leave my son on nights and weekends and that means more to me than money.
The thing that irritates me most about being a nurse is when people start a sentence with "You are a nurse, you must know about......." and then proceed to ask me about some vague or obscure health issue and they expect me to give them some wise and useful information regarding it. Nurses don't know everything about every condition that affects the human body. Lately I just tell people, "I don't know look it up on Web MD". I just don't like people thinking you're a bad nurse when you don't know the answer to every question.
I don't mean to be a Debbie Downer

but I do think that nursing is highly idealized on TV. Why don't you shadow someone for a few days, see what you think?
