It's that Time of Year Again! No, not fall, it's...

November is NaNoWriMo, National Novel Writing Month. I participated two years ago and made it to 45,000 words.
Then I quit for Thanksgiving.
Those of you who’s family lives far away, understand.
When family, especially your grown kids come to town, everything else stops.
Period. No, further comments necessary.

Anyway, I enjoyed competing in NaNoWriMo. I was able to get a lot accomplished. Besides the focused writing effort, there are local blogs and meetings available. But I think the one thing that impressed me was the encouragement.
Many participants freely encouraged with helpful advice and thoughts that helped me keep on track. Others took time from their own writing to write, I mean, write paragraphs of helpful hints.
Okay, even though I’m a pantser, I did make up a skimpy outline, and I followed it.
Somewhat—Pantser!  

​When NaNoWriMo ended, and I began reviewing my manuscript. While there were pages that were useful and relevant to my book, many weren’t. I saved every line; however, I was saddened that there wasn’t more that I could use. All those hours, while not wasted, had to be filed away for another time, another book.
​

This year I would love to do something that will ensure more of my NaNoWriMo writing is useful to my current project.
Am I the only person who had this problem?
Please, share your ideas and suggestions!​​​
