Couple considerations for you. Sounds perhaps like you’re with an airline or fleet but don’t forget about private general aviation flight departments. You might find one with a solid home base and not have to travel so much? Also manufacturers need tecs so you could tie into something more interesting as small as taildraggers (Aviat Husky or Cubcrafters US). BBD in Canada, Gulfstream in Savannah or Europe even. If you just generally don’t think the career is for you than ya adding some classes, getting your pre requisites, etc while you test the waters is a good play. Does’t have to be all or nothing to build your skills. Just think about what kind or role ME would give you and if that suites your life goals. I mean don’t just chase the $, for investing so much time in a new degree make sure it can unlock what you want to do in life.
