Sven Birkerts contemplates it:

We open our eyes in the morning and for an instantmore if we indulge ourselveswe are completely idle, ourselves. And then we launch toward purpose; and once we get under way, many of us have little truck with that first unmustered self, unless in occasional dreamy asides as we look away from our tasks, let the mind slip from its rails to indulge a reverie or a memory. All such thoughts to the past, to childhood, are a truancy from productivity. But there is an undeniable pull at times, as if to a truth neglected.
