Sea to Air
Many have gone that route before you.
Going to sea will give you very valuable life experience and it will help you to get through flighttraining since a lot of subjects are the same/simliar.
I too was able to save for the flighttraining (modular) whilst working at sea in just a few years.
Captain Playstation, im not entirely disagreeing with you but just bare in mind, what aviation is going through, shipping has been there long before. (I believe your current boss learned all his dirty tricks in the shipping industry as well).
Personally I have absolutely no regrets going to sea, I would do it all over again. I also have no regrets leaving it all behind. Work/Life balance is a lot better when flying.
