It ain't over 'til you take your last breath.

Deciding to not put up with the BS that is the airlines does not make one a failure. I almost quit on the spot putting up with parking tag BS. What are you willing to handle and what are you willing to put up with?

I grew up with my father in construction. We moved more times than the military, more times than those in the witness protection program, even more times than pilots, combined. Dad was gone for weeks and sometimes months. We'd get to move on short notice. Pay sometimes sucked. Construction projects sometimes ended with a chain around a gate and a note, "everyone is fired". Sometimes there wasn't a note. This world is going to kick you, beat you, work you hard, spit you out, and all you have to show for it is a nice headstone which may get replaced to something that is easier to maintain, or removed completely to make way for a new bypass. Life sucks, then you die. And in a hundred years, you probably won't matter anyways, except possibly to be another annoying name to learn in someone's history class.

The secret, and possibly the insanity of this, is to be happy where you are, even as you strive for something better, and no matter which choices you make. That really irritates other people who think you should be at least as miserable as they are, if not more miserable.
