Can't let go.
I have seen a lot of people who get stuck along the path in aviation. One of my flight instructor friends will not move on from instructing. He knows that even if he were able to get every student in the county he could not earn enough to adequately support his family, but still he will not move on. I believe that he lacks the confidence to try the regionals and will not go back to his former profession. All the while his family is financially struggling.
