If you'd never been through it, don't critise [sic] those who have. It's their effort and their dashed dreams and if I was them I'd be damned if I was going to let someone who'd never been in my shoes critise [sic] me for my reaction.
I have been through the process of being chopped, and of course it's very sad to have one's personal dreams dashed etc. But even at the time, I could see that it was the right course of action, and I'm just about man enough to admit to people, when the matter comes up in conversation, that the sole reason I was chopped was because I wasn't good enough. It never ceases to amaze me how many people who have been chopped simply bleat and make excuses for what happened, which makes them appear weak of character as well as (inevitably) weak at flying.
