"Novel-writing is a highly skilled and laborious trade. One does not just sit behind a screen jotting down other people's conversation. One has for one's raw material every single thing one has ever seen or heard or felt, and one has to go over that vast, smoldering rubbish-heap of experience, half stifled by fumes and dust, scraping and delving until one finds a few discarded valuables. Then one has to assemble these tarnished and dented fragments, polish them, set them in order, and try to make a coherent and significant arrangement of them."
