I would agree that the idea of humans being narrative are false. Humanity is so anti- narrative and everything that we do, or have ever done is all out of pure spontaneous action. The idea of us having truthful narratives lives doesn't seem like a realistic concept. We are random and unorganized, just look at the culture we have today. Things happen so fast and it may seem that things change out of nowhere. And the same can be said for people as well.
I would say that I see myself as a anti-narrative person because I have no control over what will happen to me in the future. Yes, I can do things that could alter my path, but still I wont know what will be at the end of it. Its better to have random things happen then for them to be planned out.
