A book starts as an idea, yes, of course. But it needs to develop from there with characters and emotional arc and plot points and all of that good stuff. If it doesn't, then all you've got is copy for the jacket flap. Of a book that doesn't exist.
So what happens when you nudge an idea, and nothing comes of it? Do you beat the idea into submission until a stroke of inspiration makes it all clear? Or do you put it aside, indefinitely?
I need to find more balance in life. Or more balance between life and work and writing. It's heartening to read the struggles of other authors on this blog. Not that I want you all to struggle, no, of course not. It's just nice to know that I'm not the only one who has moments of "What am I doing? Why isn't this book coming together? Should I really keep writing it?" It seems I'm in good company.
As of now, the future is unclear. But with writing books, is the future ever entirely clear? When you first set pen to paper, can you be completely certain that you are starting your next book, that it will be all that you dream it can be, that it will be sitting on a bookstore shelf? That hasn't been my experience. All I can do is to keep writing.
