Do you grab one and run with it?
Do you jot all your ideas down?
What happens if you're working on one story and another one is pestering you to be written? Do you stop and write it? Or do you continue on with the current one?
If you write a bunch of them, do you find it hard to keep in character?
I have at least 5 really good ideas in my head right now. But, I can't seem to concentrate on just one. I keep flipping between them, writing whatever is coming to me at the moment. It's exhilarating at times, confusing at other times. I'm excited by all of these new possible books, I find myself wishing I could write faster or that there was more time in the day. Maybe one day, one or the other will happen :)
