You will probably have to pay your dues as an RN to be competitive as a DNP. Unless you work in a hospital (especially in CA or WA) you won't make that much money as an RN. Maybe there is some other high paying state, not sure. I was really excited by the role for a few years, but over time have come to realize that I could have taken a different path that might have been less hard on the body, mind, and spirit. In fact, after over 6 years I am considering a different masters path, though might stay in the profession for longer until something comes along that is financially sustainable. I may decide to become an NP not sure yet.
Work in hospitals in any specialty will be very hard, physically and mentally and changes a person. There are many times I do feel rewarded by helping save a life, but the at least half of the time I see the failings of the health care system, rude obnoxious ungrateful infantile behavior in adults who come to the ER, and sad cases of people who don't value their own lives enough to take care of themselves. It has definitely given me a glimpse of the dark side of humanity. But then there are the positive aspects, the excitement and the ability to touch lives every day. But it is taking a toll on my body mostly and there will be a point where I can't do this anymore and I am relatively young and healthy. I just don't want to be exhausted all the time, I want to be able to have the energy for me and my family, not just strangers.
I am not saying nursing is not rewarding, but if you have a career that pays you well, is less taxing on the body and is interesting, I would stay with it. Maybe you can try to open a business that benefits humans or animals, volunteer work, or something else that gives you purpose. I would urge you to shadow a shift as an RN (that's where you'll start) and see what it is like. You will have to clean poo, be exposed to diseased carrying body fluids, risk catching diseases, and smell things that make you want to barf). And you will do this every day as an RN a hospital, day in day out. Most NPs start there because that's where the experience lies, in getting your hands dirty and hard grueling work.
