If I'm writing a novel, I'll probably get up in the morning, do email, perhaps blog, deal with emergencies, and then be off novel-writing around 1.00pm and stop around 6.00pm. And I'll be writing in longhand, a safe distance from my computer. If I'm not writing a novel, there is no schedule, and scripts and introductions and whatnot can find themselves being written at any time and on anything.
