Career Changes Support Group
This community is dedicated to the difficult challenges of transitioning from one career or job to a new one. Especially as we grow older, it can be very difficult to acquire the skills and relationships and take the financial risk to make the switch.
I say go for it. It's better to try, than to not try and never know and live with a big regret.
If you want to test it before investing the time and money, I would see if I could volunteer at the hospital. This will give you a chance to see the profession up close and personal. It would also allow you to talk to the nurses and get an idea of what it is like to be a nurse. I wish I had done it that way. Would have saved me a lot of disappointment.
Good luck with your new career choice!
