Will She or Won't She?

Nanowrimo is next month.
It starts next week, actually.
Just a few days away.
And I wasn't going to do it.
Didn't/don't have time.
​And yet ...
My muse says, "Hey, here's an idea for a scene for that book you've been meaning to write all year."
Yeah, thanks, Muse. But I don't have time.
"Ooh! Or what if they did this?"
That's a great idea! And then they could ...
Oh, wait. I can't think about this right now. I don't have time.
"But you've written a book in 18 days before. Surely, you can find 18 days in November to finish this story. Your characters need you."
No. I'm not listening.
Although ... tax season IS over. And I'll still have the evenings.
And I need to be getting ready to launch Roadtrip for Two in December.
But how much time will that really take?

Needless to say, I'm itching to do Nano again. But we'll see what happens. Because if I attempt it, I need to go in with the understanding that I might not win. Am I okay with that? I'm just not sure.
What do you think? 
​Will she or won't she do Nanowrimo?
