With writing … you must keep in the habit. After a lapse it will take you not an hour, but a week, a month, maybe, to find your mood again – that mood in which things drop from heaven. There’s no forcing it; you can’t set your notions in front of you, and stare at them till they take shape; they have to come to you whether you ask them or not. … And you have to be in the habit of that mood! Of inspiration!
