Perfectionism means that you try desperately not to leave so much mess to clean up. But clutter and mess show us that life is being lived. Clutter is wonderfully fertile ground - you can still discover new treasures under all those piles, clean things up, edit things out, fix things, get a grip. Tidiness suggests that something is as good as it's going to get. Tidiness makes me think of held breath, of suspended animation, while writing needs to breathe and move.
