I’m not going to brag and say that “I have so many and in such quick succession that I would spend all my time writing them down” … but I do have quite a number of them, and quite often. I don’t often attempt to memorialize them, but I do tend to voice them in one way or another (which means that some of them get written into emails, Facebook … and here – much less frequently these days), or best of all, volleyed back and forth with someone else in person. Fortunately we have a good group of decent conversationalists at work. That is, they’re decent people who can hold a conversation and they will sometimes indulge my occasional stream-of-consciousness flow while we’re searching for a solution to a problem – because we have a lot of problems, and I think about them a lot, and if it’s not “my idea” that solves the problem du jour, then it’s often one of the parents (or cousin) to the one that does.
When I think of things unrelated to a topic that someone else has broached, such as story ideas, plot twists, ‘better dialogue’ that should have been in the book I’m reading, for example, or other bon mots, then they generally just go back into the mix of random ideas in my head. They’ll generally reappear one day, since it’s a pretty friendly and collegial mix in there, and they speak to each other.
For the ideas that I simply must capture and nurture with special care, there’s Evernote.
