Other professions with whom nurses share common tasks: hotel maid, daycare worker, receptionist, therapist, social worker, chauffeur, coffee shop barista, customer service rep, coach, store manager, store clerk, and whatever it's called when someone pays you so that they can yell at you.
Nursing is a very challenging people-focused (I mean, we're taking care of people, right?), teamwork-dependent profession. It takes a lot of brains, heart and muscle to do this job well. I think it's the best job in the world but I know from experience that if it's not right for you (or you're not right for it) your patients, your coworkers and you will all suffer.
