Bookish Brina

I am attempting to write a one-shot.  It is difficult.  I have had a story swimming around in my head for literally two years, but have not had the guts to actually sit and type it out.  I have no idea if I will actually post it, but I like to think I will be pleased enough with the results to do it.  It will never be something that I will end up pulling to publish; not that I have a problem with the practice as I’ve mentioned before.  My story will be tied too much to Stephenie Meyer’s vision of Twilight. 

Anyone else ever tried to write a fic?  Or have advice?  I have another idea floating in my brain, a Bella/Jasper story, but I doubt that one will ever find its way on paper.
