I left and went back to school to get an MBA. I hear all the time that everyone has an MBA now and it's not a differentiator, but it definitely opened doors for me. I took classes at night and worked during the day doing inside sales for a manufacturing company; they liked my ability to understand and explain technical systems . The job was ok for a while, money was better than regional FO pay but sales is sales and not my thing. I am starting next week at Fortune 500 energy company as a Financial Analyst. There are jobs out there to be had, you just have to relate your experience in aviation to whatever business you are trying to get in to. Good luck!
