I've often thought that the worst thing we can do to stifle our creativity is to amass a large collection of our own work. Once we have a closet full of prints, there arises a natural impulse to rest on our laurels. We think, we've already done it, or we've run out of room to store any more, or all the unsold prints dispirit our motivations, or enough is enough. If we could only make self-destructing work, there would always be a void for use to fill. Remember the corollary to Parkinson's Law: The goods expand to fill the available space. Unless, that is, the space is already filled to the brim.
