The time for writing to entertain other people is over. I don't write to entertain others, or myself. This book is an instrument, a tool - and it must be hard + shaped like a tool, long, thick, and blunt. This notebook is not a diary. It is not an aid to memory, so that I can remember that on such and such a date I saw that film of Buñuel, or how unhappy I was over J, or that Cádiz seemed beautiful but Madrid not.
