If we stay where we are, where we're stuck, where we're comfortable and safe, we die there. We become like mushrooms, living in the dark, with poop up to our chins. If you want to know only what you already know, you're dying. You're saying: Leave me alone; I don't mind this little rathole. It's warm and dry. Really, it's fine. When nothing new can get in, that's death. When oxygen can't find a way in, you die. But new is scary, and new can be disappointing, and confusing - we had this all figured out, and now we don't. New is life.
