There is nothing to writing. all you do is sit down at a typewriter and bleed." what does hemingway mean? how is he bleeding?

There’s a lot of dialogue that sounds as studied as Hemingway must have intended it to sound as he declaimed it (“Let me tell you about writers — the best ones are all liars”) and stuff that’s almost certainly cobbled together from various sources. (I was particularly amused when a negative review of the movie today in The New York Times made a point of ridiculing one Hemingway line — “There’s nothing to writing, Gellhorn — all you do is sit down to your typewriter and bleed” — but failed to realize it most likely derived from a New York Times sportswriter Red Smith’s wry dictum, “Writing it easy; all you have to do is open a vein and bleed.”)
