I think jef's suggestion to try a little teaching before making a big investment in that direction is a good one. Sometimes, life within the "ivy-covered halls" of academia is not as sweet as it seems from the outside.
Personally, I loved the 5 years I spent getting a PhD. The grad-student lifestyle suited me very well. However, I eventually had to graduate and get a job that paid more money. At that point, I discovered that the transition to university faculty was not going to be as smooth as I had hoped. My clinical expertise (NICU) is not taught at the undergraduate level -- and schools
tend not to hire new faculty members to teach their graduate level courses unless they are nurse practitioners. Schools tend to assign those coveted grad school courses to their experienced faculty members. So ... as a NICU expert, but with only a little previous teaching experience, I was not a good match for the faculty job market. And I have no adult med/surg experience at all to qualify me to teach undergraduates.
So ... I found myself back working for a hospital as a NICU CNS -- the same type of job I had before spending 5 years getting my PhD. 4 years later, I was offered a job working for our VP for Nursing focusing on special projects. I investigate things for her, collect and analyze information for her, etc. I have established a nursing student extern program at our hospital and am now establishing an endowed fund to sponser scholarships
for our employees. I also serve as a liaison with all the local schools of nursing who use our hospital as a clinical site. It's a good job with minimal stress, flexible hours, etc., but it is not what I envisioned when I went back to school for that PhD.
