Andy, I am an "old" newly-graduated nurse. I graduated with my ASN in December, and I take my NCLEX this Thursday.
I spent most of my working career as an engineer (Go Purdue!!!), but after having my last 2 jobs in a row basically shipped to Mexico, I decided to go back to school and study nursing. It hasn't been easy, mostly because I had to UNLEARN "engineer-thinking", and LEARN "nurse-thinking". They are NOT the same!!!!!!
But I like it, and assuming I pass NCLEX (God-willing), I am looking forward to my 2nd career.
Good luck whatever you decide.
