Dont't start flying
Before I started flying, I finished my Masters degree in aeronautical engineering. It may have helped me a little in answering stupid theoretical questions during interviews, but apart from that, nobody ever cared.
I never had the chance to get an office job besides flying where I could use my experience and knowledge to the benefit of my colleagues and the company. In the beginning I made many suggestions to improve processes, mainly IT- related. Personal relationships, not qualification is all that matters.
Now, turning 60 years of age, I am working as a first officer with no prospect of being upgraded again, with 16000 hours experience treated like a schoolboy by arrogant 'trainers', who are abusing their power, because training, which is graded is - in my humble opinion - checking.
This is a terrible business. I am looking forward to the day when I can afford to stop.
