John Steinbeck

In writing, habit seems to be a much stronger force than either will power or inspiration. Consequentially, there must be some little quality of fierceness until the habit pattern of a certain number of words is established. There is no possibility of saying I'll do it if I feel like it. You start out putting words down and there are three things - you, the pen, and the page, then gradually the three things merge until they are one and you feel about the page as you do about your arm only you love it more than you love your arm.
-John Steinbeck
