Just want to qualify something Dicey said:
Becoming a fighter pilot "..is only hard if you don't want to do the job".
WRONG.
Contrary to what the RAAF ads say, NOT anyone can be a fighter pilot. I'm sure most (if not all) fighter pilots would say that it was bloody hard work. Plenty of guys have failed the course simply because they couldn't make the grade, not because of lack of conviction or motivation. You can have the strongest desire in the world, but at the end of the day if you can't kill the bandit quickly as the free fighter in neutral 2v1 ACM you won't graduate... Let's face it, if it was easy it wouldn't be so sought after!
However, having said that, Dicey is right when he says don't worry about it being hard. You can't undertake such a lofty endeavour because of fear of failure. It can be a huge impediment to success & it will probably drive you mad worrying even if you have what it takes.
So pin your ears back, go hard & don't let anyone tell you "you're not good enough"!!
