I write my first draft by hand, at least for fiction. For non-fiction, I write happily on a computer, but for fiction I write by hand, because I’m trying to achieve a kind of thoughtless state, or an unconscious instinctive state. I’m not reading what I write when I wrote. It’s an unconscious outpouring that’s a mess, and it’s many, many steps away from anything anyone would want to read. Creating that way seems to generate the most interesting material for me to work with, though.
