Well like I said earlier, for 4 years I had a job that had the envy of every professional pilot I have ever met. Never in a million years did I think that today I would be a line captain for a 135 and putting out resumes to majors.
As you progress in your career, your priorities change. For me, first it was accumulating as much turbine time as possible. Then it became having a salary and some quality of life. Now, I just want some stability. Not sure if 121 can provide that, but it cant be any worse than corporate aviation.
