From Ask Metafilter:

I come across sites dealing with a few here and there but there is no great collection I can find. Common examples: Hemingway's habit/belief of 500 words per day, Faulkner drinking whiskey whilst writing, Balzac drinking 10+ espressos a day, Thomas Wolfe's habit of writing standing up and his prolixity (so much so that Max Perkins had to substantially edit his work). Certain writers lived philosophies on first drafts/revisions, words/hours per day, etc. I have no problem locating famous quotes, but I'm more interested in info about actual behaviors.

Famous behaviors here.
