I've been using this technique, capn has talked about it, and told someone about it and he's doing some good stuff with it. Here's the technique:
DON'T.DO. ANYTHING.
I think the reason why you have so many stories on hiatus is because you are "forcing" them to come out. Even if you have the greatest idea the universe has ever seen, don't write it down, don't mention it to anyone, just relax and let the story handle itself. I often start stories out in the middle: a single scene where the protagonist(s) are interacting with one another and perhaps the antagonist(s). I let the characters have fun with themselves and if the scene gradually tranistions into the end of the story, that is when I lay down the basic frame work for the character designs and (more rarely) a few scene and plot designs.
Think of a story as a calf.
When the arbitrary scene comes along, that is the calf being born.
That is saying that most of the "calves" you have are born with abnormalities and you butcher them because they can do nothing for themselves or you.most of them tend to be
a) insufficiently detailed (I might have a single scene I play out or a single character I explore, that don't lend themselves to expanding into a full-fledged story)
or b) just plain bad.
So you have your "calf" and you go through all the steps to have it reach the phase you want it to. However, you are that phase and now you don't know what to do with your "calf". Should it be trained to give milk, pull a plow, pull carts into cities, should it be castrated, should it keep it testicles, etc.My problem with endings usually shows up in the first kind of stories, those that originate in my mental games as a scene in the middle. I know I want to develop them, I can usually write a beginning that leads to the middle, but I can get stuck once I get to the one original scene.
On occasion, you get an awesome "calf" that just doesn't need you tell it what to do. It just knows what needs to be done.Sometimes, though, a complete idea bursts into my head and doesn't require extensive expansion or it can be incorporated into an existing work, so I simply go with it... To date, it's still one of the stories I'm happiest with.
But usually, you're rushing and confusing the "calf" by getting the "training equipment" too early (writing the story down). Instead, just sit back on watch your "calf" grow and flourish. Eventually the "job" (ending) it needs to do will become apparent to you and you will "train" (write) your full grown "cow" or "bull" to do what comes the most natural to it (have a complete story).
This analogy is so silly XD, and a part of me gets the feeling that I didn't really accomplish anything with this.
We're discovering some things about one another and hopefully, we'll be able to help one another. 
As for publishing... Well, a book of some of my poetry would be a good start. I should to get back to sorting through the several I've written. And typing up some of the ones I've handwritten. My poetry is various, from things about life or venting out my emotions and thoughts to some fandom related pieces to silly nonsense. Sometime, I don't know when, I should gather the motivation to get back to that.
