- "You know your tail-bone? It used to be a tail. That pink part on the corner of the eye, it used to be a third eye lid. The appendix used to help us digest tough foods, now it does nothing. The story of our evolution is the story of what we leave behind, what we've discarded. Our bodies only hang onto the things we absolutely need. The thing we no longer have use for we give up, we let go."
- "Why does it feel so good to get rid of things? To unload, to let go. Maybe because when we see how little we actually need to survive it makes us realize how powerful we actually are. To strip down to only what we need, to hang on only to what we can't do without, what we need. Not just to survive, but to thrive."
