I always find that if I start dissecting the story before I've finished, I rarely regain the motivation to continue. Even though I'll reread and I might change a line a little bit before adding more on, I can't start questioning my characterisation or where I'm taking my plot (when I attempt plot, I mean.)
I become unconfident with what I do when I start getting critical.
Unfortunately, this has happened with my latest story. 2200 words in and I made the mistake of perusing it with an analytical eye. "Is he in character here?", "Oh, oh, what scene should come next?, maybe that scene should be moved here, perhaps these scenes are too short.", "The tone seems a bit wonky."
And so, I have been staring at the word processing screen all day, barely adding on more than a few words. Curse me and my analytical mind. My analytical mind that says that every line I add is pure and utter rubbish and my original intention for this story is bad, bad, bad.
I much prefer writing in one long stream and then hacking the product to pieces. It better serves the writing process and my ego.
In other related, but not directly specific news, I had my parents watching the first episode of Life on Mars this evening. Because I rock. Even better, they liked it. Because they rock too.
