I'm trying to work within the GTD process and in moving towards the utopian view it offers I've been trying to wrangle the mess of the rocks rattling around in my brain. What I'm doing now is when one of those bolts of idea lightning strikes, I scribble (more accurate than facitious) down enough to anchor the idea on a quick notes page like this:
I'll scribble down something like "send dave link to aircraft thing" which tells me all I need so that the idea never gets lost in the shuffle. It will sit on this page until I get time to decide what to do with it. It might be one of those "Do it now in less than two minutes." items or it might be the tip of the tail of a dragon that requires lots of planning and steps.
When I get time to sit and process this crap, I'll decide if it's worth keeping, which happens at times, if it's a personal item or a work related item. (I might just be on a fools errand trying to keep the two separated but I have to try.) So, if it's something to do with work it goes on a "ToDo" list which looks like this:
Here I collect all those things that otherwise might escape. This list includes stuff that aren't even available for doing such as "Wash and scrub porch chairs." which ain't gonna happen until the five feet of [bleep][bleepity][bleep] snow melt. However, I won't forget it this way.
When one of those ideas becomes viable or I can spend time creating a project for it and figuring out all the steps that might be needed or I put it onto a "Next Actions" queue page.
These extra steps are required for me so that my silly ADD brain doesn't go awry any more than it does.
That's it for now, I'm going to move on. I'll revisit this as needed.
