The tension between making it better and getting it done appears wherever people have work to finish or a product to get out: a computer, a dinner, a term paper, an automobile, a book. We want to get it done and out to the people who will use it, eat it, read it. But no object ever fully embodies its maker's conception of what it could have been. Human frailty, your own and that of others, makes flaws and mistakes inevitable.
