I suspect that you're glad the bad aspects of the job "didn't work out". Of course, there may always be that lucky relative few who spent a lifetime at a stable carrier, at good pay, and with good work rules. It's the dream that keeps people buying lottery tickets and getting commercial licenses.

Sounds like puttering around in somebody else's twin (and you're not even responsible in the right seat) might be better than a multi-year reserve regional FO who doesn't live in base.
