Today you should try to write something without using commas. Anywhere. At all. Take something you’ve already written and strip those squiggly little marks right out of the text. Rewrite your sentences so that they’re either short and snappy or else flow smoothing without interruption. I write a lot of academic stuff and long-winded sentences filled with commas do work their way into my prose. So now I’m deliberately trying to ignore commas. It is not easy!
And now I need to get back to day 15 of NaNoWriMo. I’m at 26,008 words as of last night (the comma in the number does not count!) and I’m going to go write while dinner cooks. To my fellow novelists I can only say good luck and get writing!
