Older Nurses

I always wanted to be a nurse even as a child. Unfortunately, I attend a University at the time, that didn't offer Nursing. I majored in Psychology and didn't quite finished the last year. I later had one child. At this time it was quite difficult to pursuit a nursing career, plus I couldn't afford the education without working. I later begin working in Neurology as a Technologist. I perfected this field in all areas making myself more marketable. I worked presently with patients and in the back of my mind, figured this was the same as nursing, I mean working with and caring for the patients, or should I say "clients." But, in actuality, it;s not, I missed the yearning to be what I've always dreamed to be. I have worked for the government 11 years, and later learned they would pay for my growing education as a nurse if of course, I gave them x amount of years. I have finished all courses, except for the Nursing classes. My daughter is now 20 years old. I have no problem, but I can't help but wonder how is nursing for the second career people. I am presently 47 years old and will be close to 50 went I finished. Is there any advice for this very mature student?
