“When I write, I work in series; I have several folders in which I keep the pages that I’m inspired to write, according to the ideas that pop up in my head or simple notes for things I’d like to one day explore. I have a folder for objects, a folder for animals, one for people, one for historical figures and another for heroes from mythology. I have a folder for the four seasons and one for the five senses; in another I gather pages on the cities and landscapes of my life, and in yet another, I assemble pages on imaginary cities, void of space and time. When a folder starts to fill up, I start to think about the book that can be drawn from it.
