It's been an exciting year. I've started two new children's book projects, which I hope to be able to say more about soon :)
Perhaps just as importantly, I've been learning about the business end of the industry.
You see, when you begin writing, it's generally because you have some story you desperately want to write, some diamond tale crying out in your soul. So you devote yourself, hour after hour, to crafting your masterpiece. And when it's done, some ignoramus with no appreciation for art informs you that there isn't really a market for a 120,000 word YA Western about a 25 yr old ghost who finds love after nursing his ailing mother through cancer in the Tardis.
At this point, compromising your "vision" for the sake of mere "marketability" seems horribly distasteful, and the whole business is rather like discovering that your mother doesn't actually think you're a brilliant artist.
But if you really love writing (and I hope you do, because if you're trying to break into this industry to make money, you're going to be sorely disappointed,) then you're probably overflowing with ideas. I don't know about you, but I get new ideas every day. With so many ideas to chose from, why not pick the one that the most people are going to enjoy?
Writing specifically for a particular audience is not "selling out;" it's having (and understanding) a purpose.
