National Novel Writing Month or 'NaNoWriMo' for short was started by the Office of Letters and Light. Every year in November, thousands (yes thousands) of people participate in the attempt to complete their own 50,000 word novel in the time frame of a month. That makes a goal of 1,667 words a day. Sound tough? It can be, but the NaNoWriMo website has a great community and even some local meet ups to write with other participants. Enough of my information, why not check it out for yourself?
