Since I've started the short story I'm currently working on I've had a couple ideas that are pretty cool and I'd like to do something with them but they wouldn't fit in with the subject matter of my current story. I'd like to use the ideas to create other stories but I don't want to drop the one I'm currently working on. I'm wondering what actual writers tend to do in situations like this. Do you put the ideas aside to work on them at a later date? Or do you work on multiple projects at once? I'm sure this differs from person to person but I find myself curious about what you all do.
