For years I’d been trained the way mothers of small children are, not to waste a moment of child-free time, and so I’d always got straight down to it, and the habit had carried on even after there was no real need to be so concentrated. But now, I was tired. I couldn’t do it, couldn’t produce the ten A4 pages in a morning which I’d been used to. I tried to persuade myself that, through being so slow now, every word would mean more, be more tellingly crafted. Not true. My old, rapid, if careless, style of writing was better by far than the halting, lame stuff I was turning out, crawling hesitantly over one mere page in three hours. Why bother doing it? Why expend precious energy, of which there was so little, on writing, when it would be better conserved for other things? Yet each morning the lure of the desk and the pen drew me up to that room, and I gave into it. Sometimes, sitting was painful, which made sticking to the writing ridiculous. It wasn’t even as though I thought I was turning out anything special enough to justify this regime—it was simply that for some strange reason I wanted to be there, doing it.
