I'm a registered nurse. I love people of all shapes sizes and ages. But now that I'm getting older I wish I had been a teacher. Nurses get nothing for retirement (medical I mean) We usually know as much as doctors with our advanced training these days but get blamed for what they decide ,work ungodly crazy hours etc.
Having said this I still love nursing but I'll have to work till I drop to get medical, while teachers get a great retirement package (well deserved) awesome hours, yeah, the political stuff goes on there too but these are just my thoughts. I have great respect for nurses, teachers, and social workers, by the way!! :D
Good luck in whatever you decide.
