Benish you shod listen to the advice given, Im just outa uni, and had the best years of my life, gaining a fatpl, wont beat them even...
a797 is right all the way regarding the lifestyle........ Whats the point of an 18 yr old worrying about 1K monthly repayments.... You said "" I prob wont be an airline pilot until 8 years time."" making you 26/27, whats the hell is wrong with that... your still on the young side of the average i wod say....
I think you should really think about where you are going to go after school, flight school would eb the wrong option the matter how rosy you make it look to yourself....(Denial about the current situation)
Good luck with it all anyhow
