I, as a "baby" nurse, personally love it. Some days can be super hard. The things you see, hear and deal with can be so hard. Management can suck, but not always!
I'm personally on my way to get my associates RN, and I'm excited for it. This is my first "real" profession, next to being a pharmacy tech for a few years. Honestly, there's nothing else I'd rather do than take care of people.
If you feel passionate about it, even after hearing all of these less than positive comments, then I say go for it! What do you have to lose?
