My one experience of a pilot who felt a real calling for another profession- to become a teacher, ended not well. He dedicated himself at the end of his flying career, got qualified, and moved to Cornwall to teach. Much to his surprise, the little brats didn't want to learn his pearls of wisdom, and he lasted not! If pilots leave flying, it is always for a self employed role- property development, home industry, whatever. It's hard to turn that self reliance/independence into a workplace employee culture.
