Don't be a nurse. Sure, you'll always have a job. As long as your body and your mind hold up. And being a nurse, it's sure to wear you down and eat you up.
A physical therapist makes more money, does less, and has more respect.
A respiratory therapist makes less money, does less, and has more respect.
Same goes with Speech, Occupational therapy, etc., but those jobs are fewer and harder to find.
As a nurse, you will ALWAYS have a job. Remember...there is no shortage of RN's. There IS a shortage of RN's who are willing to work in these conditions.
