Since I wrote Honor Your Ideas last week, I've put my money where my mouth is and started doing exactly that. I started with a notebook...
...and I named it ("Idea" is assumed, though maybe I should explicitly add it)...
...and I stole the index from Bullet Journal (thanks to +matt jackson for mentioning it and turning me on to that idea)...
...and I've started recording ideas within. Some of them already suck, and I'm OK with that.
I'm hoping the index will keep things fairly accessible. Bullet Journal is focused on task lists more than this idea notebook, but we'll see how it shakes out. Bullet Journal also has a color-coding scheme, but I'm not sure I have a use for any sort of categorization yet. Once I find a use for color, the color-coded pages will make the notebook even more useful.
I don't know if this will make a difference one way or another, but at least I have a more-or-less central place to brainstorm and jot down oddball ideas. And work on parody song lyrics. And think about alternate uses for geomorphs drawn on hexaflexagons, like you do.
Huh. I guess I'd better add an entry for Games In Pockets so I can start defining what the heck that's supposed to look like. Is it just a store? A line of games? A certification or license with a badge you can stick on your product? A community site for designers working on pocket-sized games?
So I'm giving this methodology a shot, and thought I'd share.
How do you track your ideas? The post-it "monitor sunflower" method? Scraps or strata of paper? Electronic to do list? Text files scurried away somewhere in the ether?
Most importantly, does it work for you?
