[incision]

I'm in a similar situation, very good pay, comfortable, family. No room to advance in anything but pay, the job is rarely interesting with a very high level of frustration due to ever present politics.

I've basically given up on fighting the politics and instea focus on working on self-starting things that can't be derailed while studying for a career realignment.

My biggest fear is staying to so long that I atrophy and/or find myself molded by the culture such that I'm unhirable.

I'm hoping to move on without taking too dramatic a pay cut (<25%).
