Nursing is a stable profession. There is always a shortage, the pay is decent, job security is always there, you can find a job in any town in the 50 states within a week of moving there. (assuming license is in order).
Pros -
pay (not great, but decent)
flexible schedule. (I know some that work 20 hours one day - sleep 4 hours at work, work another 20. then off 5 days)
job security
benefits
hiring bonus
Cons -
I know a lot of alcoholic nurses
must have a detachment to patients and surface level only compassion and caring.
burn out
rotation shift (unless you get lucky right out of school)
gross/awful things - ER, ICU, etc..
A male nurse is mostly used in ER for the best pay. Due to the fact that they can use their strength to their advantage in lifting patients to bed, etc..
The medical field is very stable and will also grow and have jobs. Pretty immune to economic downturns like the tech / communication / engineering sectors.
But there are other professions you can get into within the medical field where you are not a nurse or have to go 4 years to college. (If you are not spending 4 years in school, you are limiting yourself.)
