I don't know, I think that "the only thing which enables us to ever get anything even vaguely right is our ability to get things wrong" is very accurate and reassuring. I was thinking this morning* about something I read about middle class teenage girls' abject terror of failure and how it messes them up for the rest of their lives and their children's lives. And, perhaps that's another secret trick of the sexism meme, instilling excessive perfectionism into females with the otherwise most hopeful background, so that their natural state is to sit there unable to ever achieve something real. Maybe raising people to believe failure is the worst possible thing is a secret way of removing their intelligence before it has a chance to develop.

*If I could get up in the morning without thinking so much I would be late a lot less of the time
