This is one of you know, he talked about keystone Species, I feel this is a keystone book There's a lot of stories in here that I had heard a different things about previously But he shared aA lot more detail You can tell there is a ton of research that has been done in this book. It doesn't feel long or superfluous like a lot of the books that we read Especially the productivity systems books. He's very masterful at weaving things together through those three different metaphors throughout the whole book The coral reef the cities and the worldwide web So there is this very strong connection to this this thread  I think I'm gonna rate it 5.4-5
