You walk around in this body, but that changes according to what you eat, or your level of physical activity, or the years that pass. And inside, especially, there’s nothing constant. Every moment, you’re making a different decision. If you decide to start hitting strangers in the face, you’re a person who hits strangers in the face. It doesn’t matter if you spent the last ten years of your life behaving like a saint. Nobody you hit in the face is going to thank you for the good you did yesterday. To them, you’re just the asshole who clocked them with a right hook.”
