Someone who feels shitty a lot, apparently.

“A real writer is someone for whom writing is a terrible oral. That is because he knows, deep down, and with an awful clarity, that there are limitless ways to fill a page with words, and that he will never, ever, do it perfectly. On some level, the knowledge haunts him all the time. He will always be juggling words in his head, trying to get them closer to a tantalizing, unreachable goal. It’s a torment you can’t escape. It will reach even not the comfort of a drunken sleep, and it will shake you awake, and send you, heart pumping, to an empty piece of paper. If you have that, you can be a good writer. Congratulations. I guess.”
