Trouble with a military career, the probability of a violent premature end.
The sole purpose of Military is to kill the Government of the day's enemies.
You don't get to decide whether it's a valid decision, neither does the other side....you put your life on the line for scummy politicians.
have a look on the Canada thread, where a couple of younger people have posed similar questions.
Look at GAPAN...(big hint, search function at top of page. "Flying Scholarship")
Trawl through the various sub-forums here and you'll learn a lot more about the trials and tribulations of Airline Piloting.....poling a big shiny jet around isn't the reality!
Qualify in something that will earn you good money.....believe it or not, you'll probably end up with a home of your own, a partner and children...statistics prove this is the reality.....odd rostering anmd absences do not make for harmonious family life.....the income will allow you to afford to train as a PPL and if you save hard, maybe finance a Commercial license.
Funding a commercial license at the moment is probably financial suicide...DO YOUR RESEARCH,,,,then go forward with your eyes wide open. Good Luck!.
