You pop a few Attention Deficit Disorder Medication Pills to stay awake and keep on writing. You've run out of notebooks but hell you're in a library!
You pick a book that no one's likely to ever read, Frommer's Guide to Uglavaria and start filling up the margins with the next chapters of You leave the secular life behind for thirty years of devotion to harsh Ordeals in the sewers, becoming one with the waste and disease of civilization.
The sun rises and sets. The pills in the Attention Deficit Disorder Medication bottle diminish. You spend nineteen days writing and on the twentieth day you put down your pen and declare your efforts at an end.
