Granted, writers do more than cross our fingers and hope for the best - at least, we do if we're serious about improving. We study our craft, chat with other writers and read, read, read. And then we write, write, write - throw away half of what we write, and then write some more.
I write because I love it, first and foremost. But I must admit, I also write to get published. So I spend a lot of my time sitting at home "wishin' and hopin'."
