Bored of course.
Of course you are bored as an S/O, there's nothing to the job that a 200hr cadet pilot can't do, but it all boils down to an attitude. If work is your only focus in life you will quickly get frustrated. But if you look at what you get in return it is pretty sweet. I spend more time with my family than anybody other father I know (back home). You have so much time to do and see so many things it's staggering.
If you ever need a reality check, go home and compare your job with someone who works 9 to 5. I was almost embarrased to tell them. Lets face it, its money for jam. Compared to what I was doing it's 3 years of semi-retirement.
