This and also keep in mind that as mid mgr you become an IC to the business side of things, with its share of BS and politics. Now tell me, which one is "your team"... Mid mgr is not that much a position of power, more like a promise of decision control, but bureaucratic admin reality and twice expectations to meet.

Oh, well, there's some bright side to it too, it's all about the ppl sharing common goals, even if just for limited time. It can bring positive change.
