Circumstances resulted in a wonderful situation. After Malice, I needed to hang around the East Coast for a couple of days, alone. I considered some touristing, driving up the coast or visting some museums, but some writing tasks were piling up. I decided to check into a hotel and work on them.
It is bliss! For two full days, I have had complete concentration, total quiet, and no distractions. I just wrote, and wrote, and wrote.
I'm not sure how long I could keep it up until I miss human contact, but I recommend everyone try it. You don't even have to shower, 'cause who cares? :)
