We get up. We sit at a desk or table, and we write. We drink tea or coffee or gin and write. We listen to jazz and write. We smoke a cigarette and write.
While we are writing we do not think critically. Or worry. Or judge, or hate, or fear, or doubt, or preach. We write.
If we do any of these latter things while writing, we are not writing. The ego is writing. If the ego is writing, it's not true writing. It may appeal to other's egos, but not to another's soul.
