I say "50,000 words in thirty days."
At which point everyone I'm talking to looks at me like this.
Are you NUTS?
There are usually comments along the lines of "That's a lot!", or "How do you do THAT?"
No matter if you're writing a novel in a month or a year, the answer to that question is always the same.
One word at a time.
Earlier this year I did a post on the math of 500 words a day. But even 250 words a day will get you 90,000 words a year, a solid length for any novel. This year for NaNo, I'm not even thinking about it in words, but in hours.
I write one hour at a time. When I need to clock in more words than my daily 1,600, I write for an hour in the morning, an hour before lunch, and an hour in the evening.
If you don't want to break it up into words-per-day or time blocks, try breaking it up into scenes. Write a scene or a transition or a section of dialogue a day. The trick is to make the idea of WRITING A BOOK less scary.
Writing is an art yes, but it's also a skill, like fine woodcarving or playing the violin. It can be learned and improved with practice, one day, one hour, one word at a time. (Of course, since it's a learned skill, you also have to be willing to suck for a while. But that's a different post.)
How about you? How do you break up your projects into doable chunks?
