I love it when other people become nurses. I am in ICU, and I love what I do. There are days that I hate it, but I'm in where the drama is. Life, death, blood all over, old family feuds boiling over, some of the weirdest cases, good and bad doctors, mercy flights, young people who are really really sick and then get better (or don't). Daily, I see the sort of thing that people watch TLC for. And I get paid.
When I tell people that nursing is great, I also let them know that it isn't easy, that I hated school and almost dropped out the first semester. And that it is constantly stressful, and you'll be in a lot of situations that you won't know how to deal with. I'm not really about holding someone's hand and making their day better (occasionally, but it doesn't thrill me to the core of my being) but about learning as much as I can about the human body and its pathologies, and how to apply my knowledge. If you are a pharmacist, you know a lot. But you never get to see your work in action like we do. We are right there, with patients. I think it would be frustrating to see be, say, in radiology, because you might see something wrong with a patient, but all you can do is take an x-ray. We're different.
And if you burn out of your job, there are a million other things to do. Management, telephone triage, public health. There are niches for nurse entrapeneurs; a market that can only be filled by use. The nursing shortage is not over where I live; and there is a huge primary care gap that needs to be filled by nurse practitioners.
