Other than getting distracted, or having more story in my head than I do on paper, my biggest problem is descriptions. In real life I look at people... Oddly. Not in some deep sense, but literally. Most people see the strongest attribute a person has like redhair, or good looks. I tend to notice jewlry, the way a person walks, the persons mood. I notice the facial expression before I notice the face. I think it is because of being an actor that I look at people this way. But in writing it just doesn't work to leave out identifying factors and give all the subtle stuff. The only other thing I have to work against myself on is explaining too much back story. So much of a persons life is tied to the past, and my characters are the same way, where if you knew their past the way I do (in my head) everything they did would be perfectly understandable. Everything else I have trouble with is not so much me activly working against my self, but just working, period.things like word choice, and making sense to the reader, leaving important stuff out, I hope everyone has those problems every now and again, or maybe I just suck. I don't know yet?
