I have kept a Scrivener document for years. I haven't really used it, just dumped in new snippets, half finished ideas, things I cut from my novels and crappy half finished stories. Recently I also added rapidly written stories I posted on my blog years ago.
And now, after all those years, I am working on those stories and ideas one by one, and turning them into something new: a book full of tiny stories.
Some of the crappy ideas immediately get sent to a trunked folder, the rest becomes something.
I work on a story every day, and I find so much joy in it.
This is exactly why I've kept the file, even though I felt like throwing it away for years.
I am happy I never trashed it, because this is such joyful work!
