100% PT, current firefighter and looking to change careers.

So I left the military and within a year got a job with a big city fire department, lots of opportunities within the department to do other stuff. But it’s a department filled with tons of nepotism and a lot of who ya know. I’m also tired of having residency living in the city. I did fairly well this last year, I just cleared 100k and worked around 85 (24hr shifts).

The issue is my disabilities from the military are really starting to catch up to me and alot of times I’m in extreme pain after work. I’m concerned with the longevity of this and I am exploring other options. Between VRE, GI bill and state benefits I could probably go to school for the next 10 years if I wanted too.

Any suggestions on good careers I could work into that build off what I am doing? That also makes comparable pay? I’m ok with going to school again.
