After about a year of looking for something else, I finally did. Saturday will be my last day "flying the line," and I'm very pleased. Although there's a lot of things I'm going to miss, my children growing up won't be one of them.
I think this career should be called a "timepit" (like a moneypit, except for time). When you invest a lot of time in a career path, you expect to see a return down the road. (i.e. better pay, better schedule, holidays off) Sure, it works like that for a few folks. But for many it doesn't, and they pour yet more time into the job, hoping for a better life in the future. And so it goes.
Once I started to see the possibilities in the "outside world," I was truly amazed at how effectively the desire to fly had impaired my priorities. Sadly, I know that none of the words in this thread will stop a new commercial pilot from filling my seat in the CRJ.
