It actually might be better, or at least more clear, to say idea as a separate entity from story, rather than idea vs. story. The latter implies an adversarial relationship which isn't actually extant. Of course, the former is more than a little bit cumbersome.
Anyway, to break from pedantry, the actually crux of this post. And, to answer that query that may even now be formulating in the vast recesses of your questing intellect - I am not intentionally using as many big words as possible. And I most certainly did not imply that you had a large, empty head.
This new goal of being both informative and humorous may need a little tweaking.
I have been running every new idea that I add to my idea bank through the full developmental process. In other words, I write down the original thought/brainstorm. This, plus maybe some dialogue or exposition used to be all I did with the ideas before saving them and moving on.
Now, I also state the idea in a single sentence (usually a what if?). Then I develop the idea to a possible next level, adding specifics, but still keeping it at one sentence. Then I write a full paragraph summary, similar to a blurb, but with no attempt at keeping out spoilers.
I've illustrated the form a few times now, in other posts, so I'm not going to give an example.
This process has not only vastly improved the quality of the ideas that I bank, it is also helping to push my storytelling skills to the next level. Ideas i would have quickly moved past, I am now forced to fully develop, regardless of perceived merit. This is a good thing.
Since the whole purpose of the idea bank is to stretch my imagination, and practice telling the core of my stories, anything I can do to make the process more productive is time well spent. In other words, I am adding heavier weights to my mental whatever-it-is-a-bar-with-weights-on-it-that-people-lift-is-called.
A couple other quick notes - 1) I have now definitely been posting daily for over a month. whee. 2) As I challenged myself, so I deliver. I now touch-type all my blog posts. Okay, sometimes I peek, but I never do the two hands but only five fingers thing anymore.
