Making career choices

Hi Coaches,
I am 53 years old and have been a Registered Nurse for 30 years. I have had a lot of different careers paths in this profession and now I am wondering if I should move on. It is the typical issue that I could hold on for another 7 years and retire, but the thought of staying is hard. I went back for further education to earn my Masters a couple of years ago in hopes of finding a new path in this career. I recently got a contract job to supplement my other part time job in hopes of stimulating my interest. None of it has really felt that satisfying and I find myself uninterested, and unmotivated.
I took Brooke’s advice and looked for the good in the job and I don’t hate doing what I am doing, I am just bored. The idea of a career change at this point is scary, but staying also scare me.
Last night I started to look at your Coach training and got really excited. I am still not sure it is for me and was a bit relieved when the registration closed, but the reason why I am writing is to ask how do I know if I am just looking for something else to fill a void or if it could ultimately be the answer.
I don’t want to keep moving and trying something new only to be at the exact place I was before I made a change. I feel like that is what I have been doing most of my career. I have not been in the same nursing speciality for more than five years.
Thanks for your insight
