I sometimes wonder whether the impulse to have children is fueled by our need to create something outside of ourselves. Something that then continues on without prompting, a perpetual motion machine that allows us to always start over and make up for our parents’ and our own shortcomings. But who am I to say why people have children? I can only speak for myself. I can tell you that it is hard to find purpose and surprise just within yourself. As a writer, the question what to do with myself, how to find and keep enthusiasm for a project, particularly in times when everything around me seems to be falling apart, is a struggle. I often wish there were something other than an empty page that would allow me to externalize or, at least, distract me from my fears. On those days, when my attempts to get responses from editors fail and sources refuse to talk, when I am too lazy to conceptualize new ideas and move further into a project, when I am ready to collapse under the burden of the page—on those days, I understand why one might want to push it all aside for the sake of a child. But it seems misguided to devote yourself to someone else instead of dealing with your own struggles."
