Most of what I've written my whole life has been almost exclusively for me. Away from here, I've written two books, two short stories, three plays, about a hundred songs ... and almost none of it has ever been published. It's mostly to entertain myself, and to be a diversion from the rest of my life (which has nothing to do with writing).
Here on CHYOA, I don't get much feedback. I probably don't get many readers. Once in a while, that bugs me -- because I like what I'm doing, and I'd love to know that other people like it too. But the truth is, I'm doing it almost entirely for myself. *I* like my stories. *I* find them exciting and arousing. *I* enjoy living in the fantasies of my characters. But my emotions don't rise and fall with "success" on this site.
