I read them whole thing through at once, found some of the ideas intriguing, but like so many other materials they are- as all thought is- little more than a tool. If I understand that all such material can and does get wielded by misguided and neuroitic folks, then the onus is on us to do our own due diligence. Of course that's hard, but Deep Work IS hard. That's the whole point. Ram Dass said years ago, and he was right: I am not your guru. YOU are your guru. So hard rtio get that through.
