Get out while you still can!
But seriously, yes there is a lot of doom and gloom here two things to keep in mind 1) go to anywhere that professionals are talking and the majority of their conversation will be bitching about their job/industry etc. 2) With that in mind, yes you read these posts here but the guys are still in the industry, they still go to work every day and they still are interested enough in the industry to go on a discussion board daily about it.
Don't let it get you down too much. Your eyes have been opened to reality. It's up to you now to work out if you are ok with that reality. Yes your drop kick mate who didn't finish year 12 and is now working for metro will make 2 to 3 times what you are making in your first years. Yes you will probably have to move to Northern Australia to get your first gig. Yes you will work max legal hours. But you're flying, you are seeing different parts of Australia, doing the job of a pilot. You have to weigh up the **** v the good like anything.
