I've read the quotes. 'unhappy is the house where a writer lives' sorts of things. I don't know about unhappy, but a writer does live here.
I am not a person who writes. I am a writer.
I know this because my deepest, most soul-stirring or harrowing emotions are greeted with a rapturous: "Oh cool! Now if I can just get this into words, I can use it in a story!"
