By education, I am not a writer. The nice piece of paper says “Chemical Engineering” on it.
I don’t consider this to be a problem, however. I taught myself to be a writer largely by watching the world around me and gently crumbling it up onto a piece of paper with scribblings in English. Teaching myself to edit was a more difficult problem, since it took re-reading my own stuff and not recoiling in horror at the mistakes. But I did it.
