Um, well, it varies, doesn't it? I think it's a mix. I think you've got to have research. I would like you to come up with some original material that no one has written about or known before. And a personal angle that kind of brings it to life for the reader. It's a mix of four or five different things, and I think it's interesting how some writers do 10 percent of this and 90 percent of the other. And some people do 20 percent of everything.
