I've been flying professionally since 2007, I still love it. I still look up when jets or even (or especially!) when a small Citabria or Cessna single flys over. I've ridden the roller coaster of highs and lows, dealt with the idiocy, flown as a captain, started over as a turboprop FO. I left an engineering career for this even!
I have no regrets. I enjoy my time off a lot, but I usually have fun on my 4 days too, even as a lowly CRJ FO.
If you were so happy with your decision, why are you even back here justifying your move?
