I have sat at the computer several times and tried to think of a new story. I am blocked. I have started several stories but I stop and don't finish. But at some time I will go back to one or the other and finish it. But for now I am focusing on publishing my next manuscript and it seems that I can't think about another story while I am working on this one. It has been requested and sent to a huge publishing house. I am keeping my fingers crossed but I am not trying to be excited yet until I hear from them. This manuscript is the first novel I actully completed and it is the one that when I get it published I will feel like I am a successful author. It is actully the first book in a four book family saga. And with it I sat at the computer one night with a name of the main character and an idea and just started writing and what ever came into my head ended up on the page. The characters in this book come alive to me when I work on them they are like my children, I don't know if anyone else feels that way about the stories they write. When this book gets published I will feel like I have made it. Well I guess that is for now.
