For some time now, I've been unable to settle on a new project. When I think one up, I'm so excited about the possibilities! But as I ponder it for a few weeks, it loses that shiny-new-idea quality, and my inner editor says: "Not good enough. It won't get you an agent (editor, publisher, readers, etc.). Find a better one."
And I think up a new one, and toss it away, and another, toss it away, and another, ad infinitum.
How do you choose a new project? Do you start writing even if you're not convinced it's good enough?
