Once I start on a project, I don't stop and I don't slow down unless I absolutely have to. If I don't write everyday the characters begin to stale off in my mind-- they begin to seem like characters instead of real people.
If you want to be a writer, you must do two thing above all others: read a lot and write a a lot.
I believe the first draft of a book should take no more than three months.
I like to get ten pages a day, which amounts to 2,000 words. That's 180,000 words over a three month span.
Put your desk in the corner, and every time you sit down to write, remind yourself why it isn't in the middle of the room. Life isn't a support system for art. It's the other way around.
