I just turned 49. My youngest is 16, he's got two years left in HS. I have been in office administrative positions seemingly forever, and I want to become an RN. Everyone I tell looks at me as if I have lost my marbles. I want to do something that matters, not just collect a paycheck. Am I too old to have the education, money and time spent in school recouped? I figure I have at least 17 years (if I retire at 67). Too late to start a totally different career? Also, since time is of the essence, would an ADN be ok?
