My characters have to talk, or they're out. They audition in early scenes. If they can't talk, they're given less to do, or thrown out.
I have fun writing. I don't make it a chore. I don't have to struggle with it.
I don't want the reader to be aware of me as the writer.
Skip the boring parts.
My most important piece of advice to all you would-be writers: when you write, try to leave out all the parts readers skip.
If it sounds like writing, I rewrite it. Or, if proper usage gets in the way, it may have to go. I can't allow what we learned in English composition to disrupt the sound and rhythm of the narrative.
