Just enjoy the S/O job for what it is, fly somewhere for a lunch and have a few beers and come home for lots of days off. You will be upgraded hopefully in less than 4 years, and will have a command before all those DEFO pax who joined after you anyway.
You will be on bypass pay after about 3 years (as feighter guys come to pax fleet) so $50k a month for being an S/O is pretty good.
Relax, F/O spot won't happen over night, but it will happen
