Difficult to say whether we will ever settle down and work through all those ideas - speaking for myself, I have been scribbling like this for so many years without actually producing a short story, always intending to do more, but not finding the time. Some would say that this is just an excuse and that, if we really want to do something, then we make the time - what do you think?
A challenge might be the answer (no, I've never heard of the Nanowrimo challenge - what is that?). Are you talking about something like a certain amount of writing in a certain length of time - so that we have something to aim for?
