My best advice is to follow your dreams - and have several similar plans in case your preferred plan does not work out. Also, be prepared for something new to arrive that you never imagined in your life at some juncture in your career.
When I was a GN (14 years ago), I was told that I could not go straight into an ICU as a GN and I certainly could never go straight into an MSN program. I was surprised by this because I had a physical science background before I was a nurse and I had never heard anyone tell me this before. It was something that I had never heard from any other profession other than nursing. I was also advised to get a patient care assistant position in my last year of nursing school so that I would get more confident at the bedside. I listened to that advice - and went to a hospital recruiter. They saw my neuroscience background (before I was a nurse) and placed me in Neuro Trauma ICU. I graduated, passed my NCLEX, and was hired as a GN in the NTICU. This was such an easy transition for me because, by the time I was ready to start my new position, I already knew everyone's names, where things were, and what they were called. I just had to learn my RN job. Furthermore, I was also accepted into a master of science in nursing program the following fall. I knew that I was still green enough to need time at the bedside, so I made my MSN studies part time and took the research and theory courses in my first year. I also found out where the medical students were meeting for grand rounds and case study presentations - and I attended those as a silent observer. I studied certification manuals for ICU and neuro ICU - and passed my CCRN (ICU certification). I defended my MSN thesis a year early - and took my final assessment and clinical practicum courses last. When I completed my MSN, I applied for and gained entry into a PhD program. Recently, I finished a Post MSN certificate program in nursing education.
I tell you about my path because I want you to see that you have many opportunities - and you should stick to your guns. Some of the advice you will hear will be outdated (like the advice I got about not being able to go to an ICU or start an MSN program right away). There was a time when nurses were not very empowered. I have heard horror stories from many older nurses - I am older, too, but I am a 21st century RN. All of this opportunity is relatively new - and work environments are a lot better than they used to be. They are better because the older nurses changed many things. We are benefitting from their work....
Bottom line: Do what you want to do - and be prepared to work very hard for it.
