To write my very first rough draft ever, I used a 30-day novel-writing kit by the founder of NaNoWriMo (originally National November Writing Month). It had inspirational cards, one a day, and a calendar to fill in with my progress. I loved it! The most important part of this kit, however, was its emphasis on and support for keeping up daily word counts.
It really isn't so impossible to write a novel in a month! Less than 2000 words per day can bring you to a short-novel-length work. For an optimal word count of 70,000 to 80,000 words, however, a writer probably needs to extend well past the 30-day cycle. My daughter used the process effectively in a month-long break from school, keeping up her word counts, but her novel was not near to being done when her time ran out, and she never did get back to writing on it--not yet, anyhow (I keep hoping she will; she's incredibly gifted). Some authors may find it works to just stick to that 50,000-word initial draft length, making sure to wrap it up shortly after hitting the mark, and then go back to add descriptions and metaphors and senses later--all those things that draw in readers. Sometimes you'll add extra scenes--and at other times you'll delete redundant sections. I can be extremely redundant, I've found!
