I'm a pretty uncomplicated person. I live a very simple life with my family and I enjoy very ordinary things.

My books are love stories at core, really. But I am interested in manifestations of love beyond the traditional romantic notion. In fact, I seem not particularly inclined to write romantic love as a narrative motive or as an easy source of happiness for my characters.

In Afghan society, parents play a central role in the lives of their children; the parent-child relationship is fundamental to who you are and what you become and how you perceive yourself, and it is laden with contradictions, with tension, with anger, with love, with loathing, with angst.

Write the story you need to tell and want to read. It's impossible to know what others want, so don't waste time trying to guess.

There isn't, even now, a great tradition of novel-writing in Afghanistan. Most of the literature is in the form of poetry.

I entered the literary world, really, from outside. My entire background has been in sciences; I was a biology major in college, then went to medical school. I've never had any formal training in writing.

I will say that there is an inordinate amount of medicine in my novels, especially the first one. There are a lot of medical things that happen. A hip fracture, three different kinds of lung cancer, pneumonia, blood poisoning, and so on.

In my 20s, life seemed endless. At 49, I've had a chance to see how dark life can be, and I am far more aware of the constraints of time than when I wrote 'The Kite Runner.' I realise there is only a limited number of things I can do.

Qualities you need to get through medical school and residency: Discipline. Patience. Perseverance. A willingness to forgo sleep. A penchant for sadomasochism. Ability to weather crises of faith and self-confidence. Accept exhaustion as fact of life. Addiction to caffeine a definite plus. Unfailing optimism that the end is in sight.
