Maybe, although in my experience a piece of work is never really done, you just eventually realize you have to declare a stopping point and move on to the next project. A software's features could always be improved, a book can always be revised further, a song could always be tweaked or rearranged, you can always knock the sand castle down and try to make the parapets straighter this time. Most of my projects have a wishlist of features, 80-90% of them eventually get cut when I decided I was finally, finally going to release the damn thing.
