Yes, it’s a busy time of year between the holidays, family time, and end-of-year necessities. But you still must be writing! Never give up the quest.
Hopefully, for those who wrote words during November’s NaNoWriMo, that was only the start of a long process which you will see to the end.
The first step is to look over what you wrote last month, and to dump/delete/trash all the unnecessary words, scenes, chapters, characters, and unrelated stuff. The first year I did this, I cut 47K of my 50K NaNo words. I confess. I am a NaNoWriMo babbler. In my defense, by forcing myself to babble I often come up with some surprising to me things. One year, I gave my middle school characters an assignment by their teacher to write their autobiographies. Of course, none of those autobiographies made it into the final story, but it was a great writing exercise for this author to get to know her characters better.
Delete. Delete. Delete.
By getting rid of your babble (excess words), you will find that what’s left is a very nice skeleton of plot and character to soon start fleshing out.
