I agree that flying "is in the blood" - christ for all the sh*t you have to go through to get your licences - you really have to want it.
For most people flying is only a dream and a much larger percentage dont fulfil their dream, than those who do.
I have wanted to be a commercial pilot for as long as I can remember - yes I look up when an aircraft flies overhead, yes being near an airport and lookin at the aircraft is exciting, and yes I do watch programmes that contain aircraft - guilty as charged your honour!!!
What I am trying to say is that it is something you have to be 100% committed to, not just something you thought up oneday at college and though "I know im going to be an airline pilot!" - this is something you have to want and want badly.
I have had to work and save and work and save, working sh*t hours for a sh*t company to fund my training so far - just ask yourself-
"would I do that?.....do i want it that bad?"
Good luck Sir!
