I love my job. I started out on Med/Surg 10 yrs ago, then to Neuro ICU, and stepdown. I now work as an Occupational nurse at an auto component mfr. I would never have tried this specialty without having at least a couple of years under your belt. I have been in my current job for 9 years, and only had 2 1/2 in M/S, and every ICU where I worked. I still rely heavily on my hospital-based experience. If it was me starting out, knowing what I know, and having the experience I do, I would still do it the same way. I think it would be wiser to get some time in. Nursing school doesn't end at graduation. I gain new experiences and knowledge every day. As far as the Admin position: better you than me. Been there, done that. I like being an Indian, not a chief.
Good Luck
