Some advice on writing?

everyone's right. Read. read different authors, different genres. read two books at the same time. Find what works for you and what isn't working, learn to identify the voice/tone, watch how characters develop through the action. Then, you're ready to try writing.

as for that, if you're having trouble getting started, don't think about it. Just sit down, grab hold of an image (you're got some in there, i know) and write about it. Write as much as you can. No story is ever done in one draft anyways - so don't worry about grammer and plot and all that shit in the first one. Just get it out there. The real work in writing comes after, and you get to revise that 1st draft garbage into something more coherent, then you revise the 2nd draft into something cleaner, then you revise and revise again.

Jam it back in, in the dark.
