Dead-end at a crappy regional (well any regional) with no upgrade in sight should cause anyone to question the career. I'm really only hanging in there because I tend to be goal oriented to a fault and I can afford financially to sacrifice rapid career progression for max QOL.

In your shoes I might be looking to break into some kind of real career and CFI on the side. That way you could stay connected to aviation and maybe do part-time corporate. In case the pilot shortage ever comes about you would still be current. Maybe you could get into corporate full time.

If you can build PC's, you might get a job as a tech then do some network certification and the MBA...that would set you up to be an IT manager at a mid-size company. To get into IT at larger companies, they usually look for formal education and certification (CS, EE, Computer E, Math, etc).

If you have the personality traits, you might be able to get into sales of sort.
