I think it should be compulsory reading, especially for those approaching the end of their PPL training.
A pilot friend of mine was recalling a particularly sobering moment flying IFR with his family on board. The details are unimportant but it was clearly one of those times when, as the saying goes, it is better to be in the pub, looking at the sea and wishing you were out sailing, rather than sailing in bad weather, looking at the pub on terra firma and wishing you were in it. Aaaaanyway, as he started his tale of woe, he said these words:
"I was around 2,000 hours. You know; that point where you think you know it all and then realise you know nothing."
That's stuck with me.
