You know, it's not about the money, right? Because if it was, no one would write. There's never any guarantee that you'll sell a book, and even if it's sold it doesn't mean they'll actually publish it (I had that happen once -- it ended up that I got to sell it a second time). If it gets published it doesn't mean it'll show up in very many stores, and if it shows up in stores it doesn't mean anyone will buy it.

So you'd better write what you want, preferably for who you want. I made that mist...
