The only way I got a story told was to suspend my worldbuilding and concentrate on an individual story. It's a psychological thing. I had a thousand great ideas (which always look great when they're just ideas) and I had to make them a promise: I'll get back to you. You're all wonderful and special and each one of you deserve one or more stories, but right now, for the time being, I've chosen this particular idea and I'm going to pursue it until I pound it into a story and get the thing (self-)published. All the other ideas were desperately jealous and gave me no end of grief, but I just had to ignore them until that one story got told.
Once I had that one done, I knew I could do another. Since then, the other ideas are still jealous and they still nip at my heels, but for the most part they've learned that everyone has to wait their turn.
