Couple of things to consider.
If you dream of an employees career in aviation and you are now 44, it is simple - your chances are almost nothing. The only way you get a job is by knowing somebody who gives it to you. The normal labor market, applications and initiative letters won't bring you anywhere, as companies tend to suspend investing in you at about 45. Simple stupid, but that is the way HR departments work nowadays.
If you consider being selfemployed or built a business and give a !!!! for HR departments, you could do and do good for the next 20, 30 years. You not only have to own your career path, but have to care for further education as well. Let me assure you - this is the better way to have fun, and at that age, probably the only one.
