Worth the sacrifices? Tough call - for some maybe, for others maybe not...I ::think:: I'm of the former?
I can't tell you how satisfying my job is on a good day. That I was born for it doesn't come close to cutting it...Just know that at times you'll be flying with guys that are flying for a completely different reason - they don't love it like you do...A lot of guys I flew with while in ORD didn't even like driving a car. In my personal opinion, if you don't like operating ground machinery, you have no business in the front end of a 500 knot flying machine...Not only is that a tough pill to swallow, but they will try and bring you down (not intentionally, of course, but will nonetheless).
