I am at my happiest when I'm problem solving and a large part of writing is for me a lovely labor in problem solving. Every act of discovery in writing involves a process of figuring out why I'm not seeing what I need to see. Niggling feelings, discomforts, a sense that you've forgotten or overlooked something, a sudden curiosity about what if here? - these are priceless. They are the bases of problems and lead the way.

I had a tough childhood, yes. I was born in rural Bangladesh to parents who had had no education beyond high school. We moved to the UK where I grew up in poverty, in some of the worst conditions in a developed economy, before moving to the projects - heaven - and I went to unremarkable schools before going to university. My father was a bus conductor first and then a waiter, and my mother a seamstress.

Writing is indeed essential to me. I have been writing for a long time but not for publication. I'm sure there are many, many people who do the same. The rewards of writing are in the process and not the product - not just for me but for others I have met.

There have been studies concluding that most people mostly know people only within their own social class - although such a conclusion would hardly surprise anyone. I think there's evidence to suggest that it's even narrower - the great majority of friends of Ivy Leaguers, for instance, are Ivy Leaguers. This narrows the pool of people who can write fiction cutting across class boundaries that's informed by their own personal experience.

By delivering experience, novels can alter the stance we adopt toward news - not much, I'm sure, but they can make it a little more difficult for us to consign "other people" to our tidy boxes. Widening our imaginative life might - it's not hard to imagine - also develop our ability to contemplate counterfactuals and our capacity to speculate about how things might differ from how they're being represented.

I'm not sure, however, that what I have amounts to faith in the sense commonly understood. I have difficulty understanding the function of the word "believe" in the realm of faith, a basic term in the grammar of every creed.

I don't want you to think that I'm being willfully obtuse, but I've never really grasped how point of view could be regarded as a matter of choice independent of story. Point of view is intimately interwoven into the story that you want to tell - it is an aspect of it.
