What age did you decide to go into nursing? 40 When did you graduate? Just completed the pre-reqs for a RN program. Application submitted this past January and just waiting to find out if accepted. AND... what field were you in prior to that?? For the past 14 years I have worked in the Computer Networking field. Prior to that I was a Medic in the US Army. So at 25 you are not even close to being too old. At 40 I decided to change careers to do something I am passionate about. I will even be taking a pay cut with this change, but I would rather do something I love for the next 25+ years. I should have completed nursing school when I got out of the Army 14 years ago, but it wasn't the right time for me. I have no regrets because I believe the path I took to get where I am today was right for me. You need to do what works for you.
