Quotes:
“...I think this one particular idea of work as imagined/work as done has been thought about a lot in the time since this book was published…”
“What is this measure of successful work? What is this way that we would categorize something as successful, if it’s not, not having accidents?”
“It’s a misinterpretation of Heinrich to apply the ratios.”
“And that sort of criticism of the old to explain the new, I think is never as firm a foundation as clearly explaining what you’re sort of underlying ideas and principles are and then building on top of them.”
