From Spark: How Creativity Works:
Close is fond of saying "Inspiration is for amateurs, and the rest of us just show up and get to work. But so much of it comes out of the process ... if you try to preconceive everythting you do and conceptualize it, you're gonna do the same thing over and over. If, however, you just get busy and things occur to you in the process, you make the rules and therefore you can break them." P13.
