Can't Sit Still

I have been very antsy to write today. My mind keeps drifting and I have to stop myself from starting to continue writing my novel in my head. It kills me to stop myself from doing this. Occasionally, I jot don't some notes, but I miss sitting at my computer at home, engaging the keyboard in a fingertip assault. After work, I have my commute into the city, then I need to finish some homework, then meet with my professor, then class. I will not be able to tap away until close to midnight.
