If outlining is not for you then try this, come up with a one sentence story. Like...
The fox chased the happy dog that ate the pig.
Next ask questions. "Why was the fox chasing the dog?" or "Whose pig got eaten?"
Once you hve a good list of questions , work out answers to those. That should give you a skeleton of a story that you just have to flesh out.
Just a suggestion, might not work for you, or it might.
