I am an attorney who went to nursing school, so I'm "just a nurse" to some people now. Generally these folks hate their job and hate that you went and did something that you wanted to do, rather than stay in something you hate because everyone else expects you to. I cut people like this out of my life.
I'm a master level psychologist, got into nursing for more job opportunities. I loved my work before, but it was too hard to find a new job when I needed it- so I had to get into other areas like research. That ultimately led me to nursing.
Second career nurses bring a very different perspective to the nursing profession IMO. We know about the corporate world, nonprofits, the healthcare industry, and so on. So we are a bit more thoughtful on the "way it's always been done". I see this as our collective strength. We have power to make really great changes, if we can figure out how to wield it.
