I am agreeing with you that not everyone has succeeded but its definitely not the majority, otherwise PPRuNe would be filled with many more young sour grapes.
I'd agree it's not the majority, but I do wonder how many who do fall by the wayside (and some definitely do) would have the bravery it would need to post their story on Pprune?
