I'm as fast at the beginning as I am in the middle and in the end. Probably that's why in 25 days time, I did 150,000 in my first draft of my current WIP, 6,000 words a day. My previous first draft of a previous work? Same. 120,000 words in 15 days. My 2nd WIP, 16,000 words in 3 days. I usually write the plot in a different document and that's how I write the entire story, by the plot alone. I once wrote an entire 250,000 word novel (trunked, definitely) based on one scene that I daydreamed about. I wrote that work in 2010 and last night I found it in a red CD-R. It was nice to revisit that. I was like Whoa there horsey. Of course it depends on how much your characters nag you to write what they're gonna do. When you have your characters constantly nagging at you, you have to write it, and mine nag all day and all night long, so you literally have me sitting in front of this netbook from my waking hour till my going to bed hour, excluding the short breaks I take to listen to music, eat my meals and shower. I rarely watch any TV. There has to be something on that I love, like Days of Our Lives General Hospital Pretty Bad Girls or Deadly Women or just a random Adam-Lambert appearance on TV.
