This is the first time I have read the intro, and I had the realization that I am not very attentive to nature! There is so, so much in here that is around my eyes all the time, but for some reason, my eyes don’t see it. It’s like I’m walking around blind to what’s all around me! So much in here. I feel like I would have to read it 10 times just to get the surface of all of the knowledge in it!
