Career Advancement after working in the ER

Hello ER nurses, I was wondering if anybody can give me a direction in the sense of what I can do after a few years of working in the ER. Any career paths and opportunities for advanced degrees?

Whatever you make of it, I guess that's what it'll be.

I have seen fellow nurses from the ER go to ICU, IMU, PACU, Case Management, hospital management, Hospital administration, pre-op, post-op, day surgical centers, stand alone urgent care, school nursing, NP, CRNA, radiology, cath lab, and several other areas.
