We have become archivists of the self, I thought, curators of a life half-lived. Each countless photograph of a wonder, of dinner, of a view, of our children, of the utter banality of our everyday lives, was not a memento, a way of remembering the things we did, but instead evidence of the poverty of our engagement with the present moment.

Our photographs are not memories; they are advertisements, billboards for a life we are too preoccupied to live.
