I'm pondering a mid-life career change, and several friends of mine have done sort of the same thing, and gone into nursing. I'd like to hear just general observations on the job, or any advice from those who have chosen this career. How rigorous/difficult was the schooling for you, what different types of positions are available within the field, is it a financially good move, do you have any reservations/regrets about it, how physically taxing is it, etc, etc? My background is in hospitality/ restaurant, and my education was liberal arts oriented. I'm looking for something that pays a bit better and has a little more upward mobility than what I'm doing now. I'm almost 40. I'd like to hear everyone's thoughts, please.
