Because I've sold more of them and because I'm writing fewer in a given year. And the latter part isn't a bad thing, either, because I'm liking a much higher percentage of the ones I write, and because I wasn't really all that pleased with writing twice as many in a year. (Various factors there.)

But there is a down side, even though the whole is a good thing. The way I manage dealing with rejection is that there are always several other things out there in circulation, so if any one thing gets rejected, it's one out of a large-ish crowd. (When I started submitting stories seriously, I didn't prepare one for submission. I prepared three.) Also I deal with it by viewing short story submissions as a dose of hope: on any day, any day at all, something good could happen, in that I could sell a short story. So I need to adjust my brain to dealing with a smaller level of cushioning and a smaller dose of hope. I think adjusting the brain is the right answer -- trying to get back into a short story writing frenzy with mixed quality of results (or with consistent results neglecting novels and other stuff in my life) is not the answer. But it is a change I need to perform on my outlook.
