Despite Gorky's approach, I think he's probably right - on most points!
I've said it before and I'll say it again: do not even think about becoming an airline pilot unless you really, really, really want to be one. And that means being prepared to make all the sacrifices Gorky has so inelequently, but so effectively spelt out!
Think before you spend, before you sweat, before you stress, before you sacrifice. Then commit.
