My father told me the same exact thing, as far as the "sleeping arrangements." I appreciate your advice very much, I fear the idea of being a mechanic, or secretary with a military title, ya know?
Nothing wrong with being a mechanic. Those are the guys that made my jets safe and a weapon system instead of just a neat ride. You'll work your butt off and be rewarded with making the mission happen.
I've had 18 year olds work non-stop just because their name was on the side of the jet as Plane Captain and that meant it was theirs and I got to borrow it but that pride of ownership showed for them. It's an honorable profession!
