To fic or not to fic...?

That is the question.

*thinking thinky thoughts*

I've had an idea for a J2 fic sloshing around in my brain for a while now.  But I'm just too damn lazy busy to type it out.  It would definitely be a looong-ass fic, and I am sooo tempted to sign up for bigbang just so I can make myself write it.  But I don't want to put pressure on myself (like a specific time limit) either.  Ugh.  What should I do? 

Just in case you're wondering, the fic would defnitely be Jensen/Jared, possibly NC-17 (not sure about that quite yet though), a little bit HarryPotterStarWarsLordoftheRingsHeroes-cracktasticness but NOT a crossover.  Yes, I did say cracktastic, but believe it or not, it's a quite serious storyline with lots of twists and turns....involving folks with special powers; folks like JDM, Chris Kane, Steve Carlson, Sandy McCoy, Danneel Harris, Alona Tal, CMM, and possibly Mike Rosenbaum and Tom Welling....along with a few other people you may recognize.

So what's the verdict?  Write it on my own time?  Sign up for bigbang? Don't write it if my heart's not in it? It sounds too weird; don't waste my time?

Just........help, plz.  -_-
