I must write for two hours each day or I go insane.
Insane - Uncontrollably angry. Dangerously distracted. Prone to muttering to self in unintelligible, quick fashion that may cause others to believe I am speaking in tongues. Moving in response to thoughts unrelated to my own physical condition.
Two - Anywhere between one and six.
Write - Making pictures in my head. Sometimes the pictures move. Sometimes they talk. Sometimes they hurt one another, or are already hurt when they arrive. Often I crunch the pictures up like pieces of paper and squeeze them until they run down my neck and through my arms to dribble out of my fingers. When I'm working well, I can reconstitute the pictures into words in a way that "looks" like they did in my head. When I'm not working well, it's all stick figures with bad attitudes and nothing interesting to say.
Must - Bound by an imperative, essential requirement and obligation to myself.
