"You can write great books," the great man continued. "Or you can have kids. It's up to you." [...] Writing was a practice. The more you wrote, the better a writer you became, and the more books you produced. Excellence plus productivity, that was the formula for sustained success, and time was the coefficient of both. Children, the great man said, were notorious thieves of time. [...] Writers need to be irresponsible, ultimately, to everything but the writing, free of commitments to everything but the daily word count. Children, by contrast, needed stability, consistency, routine, and above all, commitment. In short, he was saying, children are the opposite of writing."
