First Fic?

Well, I have always thought of myself as a good idea maker for fics. But getting my Ideas to full 1k 10k words os something I for some reason cannot do. A few years ago I tried to write a Naruto (yes, yes, I know) fic where I deconstructed the typical Harem story where the other men in the world is pissed off that Naruto is hogging all of the girls to himself and then they try to kill him but.... Naruto is the dreaded Canon sue and only Shikamaru (Yes, yes, I know...) Can make a master plan to stop him.

See? Great Idea, but no execution. I could not write a fic. Until now. ( Mind that it will take FOREVER for me to write, but... who cares!)
