To NaNoWriMo or Not To NaNoWriMo?

I was reading a book this morning (I know, it's hard to believe) and it said something about the conflict between our right and left brains. This is EXACTLY what I've been experiencing the past couple of days.

So what does that conversation between my brain halves look like? Take a peek:

RIGHT BRAIN: You know, you really should try this NaNoWriMo thing. I think you'd love it.

LEFT BRAIN: Are you KIDDING me? Where in the heck would you find time for THAT right now?

RB: Um well, I could do it. I could. I mean, there are moments all through the day that I waste. So I could fill them up with writing.

LB: Yeah, right. Something will have to give. Are you ready to give something? And besides, what makes you think you can write a book. That's like, HARD!

RB: Well, I, you know, write every single FREAKING day! (Almost.) I have tons... thousands... of blog posts you know....

LB: A blog post is different than a book. There's this thing called PLOT. What do you know about plot? Nothing!

RB: Well... what better way to learn then to try. You know, I can TRY at least!

LB: Well, I guess so, but still, it's going to be hard to write something if you have no idea of the direction it's going.

RB: I sort of have a direction. I wrote those four chapters years ago, remember? Back when I thought I could do this? And I just re-read them and, guess what? They aren't half bad!!

LB: They're pretty bad.

RB: It's got some awesome dialogue, you have to admit.

LB: Dialogue is no plot.

RB: You have to start somewhere. Seriously, you KNOW it would be fun to try. You know it! Who cares if we don't know how. And it's not like I'll try to get published or anything. Sheesh.

LB: Well then, why waste all that time if you don't have a goal like that? How can you even justify the amount of time this will take?

RB: It's on my bucket lists... that's how! Those lists (both the bookish one and the whole life one!) justify ANYTHING!

LB: You can't do it.

RB: Yes, I can.

LB: Seriously, you can't.

RB: Oh yes, I so can.

LB: Nope.

RB: Yep

LB: You are not going to do this.

RB: I am. I am so going to.

....and on and on and on it goes.

I'm not kidding this is totally what's been going on in my head for the past few days. One morning I was totally excited about the idea. By the evening, I was thinking, no way. Can anyone relate? How do you overcome this conflict?

And... you ARE doing NaNoWriMo this year? Please, if I do this I need lots and lots of cheering friends, as you can see. We need to fight that dumb left brain!
