From an interview with David Mitchell, who wrote a novel that I tossed down in fury after reading a particularly fine passage:

INTERVIEWER

Can you remember when you first knew you wanted to be a writer?

MITCHELL

There was no single epiphany, but I recall a few early flashes. When I was ten I would be transported by certain books—Ursula K. Le Guin’s Earthsea trilogy, Susan Cooper’s fantasy novels, Isaac Asimov—and burn to do to readers what had just been done to me. Sometimes that burning prompted me to start writing, though I never got more than a few pages down. A few years later I would indulge in a visual fantasy that involved imagining my name on the jacket of a book—usually Faber and Faber—and I’d feel a whoosh inside my rib cage.
