Yahoo! I'm starting my 3rd revision. You're thinking - oh, she's just making sure she used commas correctly - she's prety much done.
Uhh, no. Between the first and second drafts I had to dump three secondary characters by merging them in with other characters, and my theme shifted a little. I also had to fill in all the parts I skipped over in the first draft to keep myself from getting stuck. So this second draft is probably what you'd normally call a first draft. NOW I can start revising it.
Still, it's a good thing (aagh - delete that - cliche!)
