In an essay for GQ, he provides a decades-later response to an esteemed literary figure's advice not to have kids, if he wanted a serious career as a writer. The piece closes:
And those four “lost” novels predicted by the great man's theory all those years ago? If I had followed the great man's advice and never burdened myself with the gift of my children, or if I had never written any novels at all, in the long run the result would have been the same as the result will be for me here, having made the choice I made: I will die; and the world in its violence and serenity will roll on, through the endless indifference of space, and it will take only 100 of its circuits around the sun to turn the six of us, who loved each other, to dust, and consign to oblivion all but a scant few of the thousands upon thousands of novels and short stories written and published during our lifetimes. If none of my books turns out to be among that bright remnant because I allowed my children to steal my time, narrow my compass, and curtail my freedom, I'm all right with that. Once they're written, my books, unlike my children, hold no wonder for me; no mystery resides in them. Unlike my children, my books are cruelly unforgiving of my weaknesses, failings, and flaws of character. Most of all, my books, unlike my children, do not love me back. Anyway, if, 100 years hence, those books lie moldering and forgotten, I'll never know. That's the problem, in the end, with putting all your chips on posterity: You never stick around long enough to enjoy it.
