"he should have more faith in himself and think about how he will look when he's gone, not now, he seems to have forgotten this a little bit "

I dont see why he should be criticised for leaving a personal experience on the Ridgeway out of his book. It wasn't a book about that and he's entitled to pick and choose what he likes to write about. He doesn't owe a duty to mention any such experiences to anyone, he's his own man and I think he'll look OK when he's gone.

Incidentally, he thinks ley lines are a delusion. Is that something else he has let the side or himself down over? No, it's what he happens to think - but that too wasnt central to the purpose of his book.
