Bloody hell this is a good quote. From Don DeLillo (via James Tata):
I was a semiconscious writer in the beginning," he writes. "Just sat and wrote something, or read the newspaper, or went to the movies. Over time I began to understand, one, that I was lucky to be doing this work, and, two, that the only way I'd get better at it was to be more serious, to understand the rigors of novel-writing and to make it central to my life, not a variation on some related career choice, like sportswriting or playwriting. The novel is different...We die indoors, and alone, and I don't mean to sound overdramatic but you know what I'm talking about. Anyway, all of this happened over time, until eventually discipline no longer seemed something outside me that urged the reluctant body into the room. At this point discipline is inseparable from what I do. It's not even definable as discipline. It has no name. I never think about it. But there's no trick of meditation or self-mastery that brought it about. I got older, that's all. I was not a born novelist (if anyone is). I had to grow into novelhood.
