Many years ago, I met a commercial pilot whilst I was still at school....
He gave me some advice which I did not heed:
Go and get the best paying job you can, and use that to fund flying aeroplanes as a hobby.
I disregarded that advice, went to Uni, got the Aero Eng Degree, sponsorship by airline, now a captain with a UK airline.
In retrospect , and on balance, I think that the gentleman's advice was probably correct, although I couldn't understand why at the time.
Unfortunately these days, much of the fun of flying aircraft has left this profession, which has poor working conditions, poor pay -in comparison to other "elite professions", and more and more constraints placed on it.
Other factors to consider are whether you will be able to get yourself out of bed at 4:30 am to go to work, and probably not be home until the schoolkids are walking home in the afternoon. By the way , you will have to do this throughout your working life until you retire at 60 years old. You will be tested constantly throughout your working life...unlike doctors, lawyers, to demonstrate your continued competence, sometimes after a long working week with disrupted rest.
If you love aircraft to the detriment of everything else, then none of this will dissuade you, and you need no advice.
Go and study a subject which you think you will enjoy, and which will reward you handsomely.
Good luck sir!
