Kazuo Ishiguro: how I wrote The Remains of the Day in four weeks | Books | The Guardian - http://www.theguardian.com/books...
"Many people have to work long hours. When it comes to the writing of novels, however, the consensus seems to be that after four hours or so of continuous writing, diminishing returns set in. I’d always more or less gone along with this view, but as the summer of 1987 approached I became convinced a drastic approach was needed. Lorna, my wife, agreed." - Maitani
"Until that point, since giving up the day job five years earlier, I’d managed reasonably well to maintain a steady rhythm of work and productivity. But my first flurry of public success following my second novel had brought with it many distractions. Potentially career-enhancing proposals, dinner and party invitations, alluring foreign trips and mountains of mail had all but put an end to my “proper” work. I’d written an opening chapter to a new novel the previous summer, but now, almost a year later, I was no further forward." - Maitani
