Henry Miller on Writing

I have been reading Henry Miller on Writing edited by Thomas H. Moore. I have always admired the acumen and artistry of Miller's writing. This morning, I read this passage and it spoke to me not only when it comes to writing, but to art in general. The point of writing or art in general is not to become this alien, novel rarity, but to tap into the human or natural stream of who we are. The goal is to get inspiration from the familiar, the lost souls in the maze of cubicles, the quietly lonely no one on the bus with a grocery cart, and all that is around us that is at our periphery that we know is there, but we are too busy to notice. 
The ability to tap into this "blood of life" or the current that is every sentient thing on this rock hanging in sea of stars is the genius, I think. It is not "THEM" we write or paint about, but it is us. Join the current of life with me.
