I've had the great fortune of interviewing many acclaimed authors. They always have much to say about the craft of writing. One of the questions I've asked often has been What has surprised you about the writing life?
Hemingway also made the statement that, "There is nothing to writing. All you do all you do is sit down at a typewriter and bleed." Leave to good ol' Papa Hemingway to be his dramatic best, but he has a point. We bleed creativity.
