Yep. Not only do I have the creativity out the wazzoo part, BUT it also comes sporadically - plus - hand in hand with a terrible memory.
Solution: I have a google docs and gmail account where I have a email saved as a draft of all the bright ideas I have for premises.
I number them, have about sixty of them, begin with a brief description, almost always a title, sometimes I hunt down an image, figure a MPAA rating it'll likely be written for, name the double genre, and then... wait.
In the google docs area I have spreadsheets where I've sorted out which are pie-in-the-sky productions only a studio could produce, those a small studio could pull off, and those that it's theoretically possible that I could eventually produce.
Start hammering out the stories on spread sheets.
Add ideas when they pop up.
Move plot details around.
Come to any random project that pops in your head. Drop them when your fickle muse abandons you.
At some point any given story achieves content critical mass AND MUST BE DONE or written up AND SOLD, or at least put on the meat market.
It is sad
It is sad when someone has a single idea, like a little birthday cake candle, that they alternately brandish ahead of themselves like a guiding beacon and then clutch to their little heart.
"Dude.
You'd better learn to start putting out ideas and concepts like a sturgeon puts out roe.
Not all of your babies are going to survive.
Learn to let go."
A film idea is a commodity like a lump of coal or a piece of gravel.
Here's how the film world sees any of our ideas:
Pick one, or two. Those are yours.
Seriously, there are some film ideas which are more or less practical to produce within a person's resource limitations.
Develop those, not necessarily the most grandiose ideas.
