I'm desperately afraid of dying unsatisfied. I will never see all the things I want to see. But I do derive pleasure from recounting my stories. And so I'm putting stories down. All of them. All that I can remember anyway. And hopefully when I'm old, or simply decrepit, I'll be able to be content. And I'll have my stories to keep me company.
I write them when the mood hits, when a memory presses to be released. Sometimes I read the stories over and edit them, and sometimes I just spit it out in the way my brain releases it and hit publish.
