If YOU want both careers equally, then I would certainly suggest nursing. There is a shortage of RNs. The job pays well. The only downside is that you may be put on any shift if you work in a hospital or nursing home. This includes working holidays. Nurses in hospitals and nursing homes work all hours. If you prefer, you might consider working as a school nurse. You work the same hours as teachers.
Check the Occupational Outlook Handbook on line (
