promise

I've lost my way a little recently, with my writing I mean. I finished my last writing project, John Mann - At Day's End, and published it over 18 months ago, and I've struggled to find a project to focus on since then. I've had plenty of story ideas, and that's probably the problem, I've had too many ideas. It seems like a good problem to have in many ways, too many ideas, but a problem is a problem no matter how it presents itself. I've followed each of those ideas for a distance, a period of time, be it a matter of hours, days or weeks. I've outlined the whole story of one, written a couple of chapters of another, noted detailed dialogue from a scene for a different one altogether. I'm a bit like a dog whose attention keeps getting sidetracked from the stick, to a scent, to a butterfly, to the ball. I focus intently, for a time, and then something else catches my attention and I move on. Is this a personality disorder, a form of writer's block...
