This is very much the opposite philosophy of the ETS foundation, which seems to be all about having the right things to help you survive. I think this was the most interesting paragraph:
Primitive hunter-gatherer type cultures were very good at doing nothing. Exactly how well they did this is difficult to determine, however, because doing nothing leaves nothing behind for the archaeological record. Every time we find an artifact we have documentation of something they did; yet the most important part of their skills may have been what they did not, and there is no way to discover what that was by studying what they did.
