Here's what I wrote: I sold my first professional short story in 1982, when my first child was small. It went to an anthology, that turned into an annual event, and the editor really liked my work, so for the next chunk of years, I'd write 2 or 3 shorts and a novel, would sell most of the shorts to that same editor, zilch on the novels.
Then several things happened. I realized I was in danger of becoming a one-editor writer for a fairly specialized market. I joined a local writers group that had a bunch of Clarion grads and other critique-skillful people. I'd networked enough at cons to set a strategy for getting an agent: make up a dream list, get an offer, call the agent at the top of the list.
The critique group tore apart my current attempt at a novel. I went home, cried, screamed, set aside my pride, came back, asked for one-syllable-word explanations, worked my tail off on craft. Eventually, that book (the 6th or 7th I'd written, depending on how you count partials/rewrites) became my first sale. Got the offer (after a 2-year wait), called the agent of my dreams -- hooray! Seems my writer friends had been telling him about me and he'd been waiting for me to have a project he could represent. In the meanwhile, I started selling shorts to top markets like ASIMOV'S, F & SF, the second STAR WARS antho, and others. In other words, I'd broken out of the one-editor trap.
Fast forward through a poorly-selling 2nd novel, a decision to not change my byline for the third (this was in the prelude to a personal meltdown that lasted several years, so I was not exactly rational), then a long dark stretch. Sold a few shorts, some of them among my best work, kept slowly healing as I struggled with being a single working mom with a troubled teen.
Then came one of those amazing breaks that sometimes happen. The chance to work on a Darkover novel with Marion Zimmer Bradley, a dear friend who'd stood by me through the hard times. I don't have words for the gratitude for that boost back to writing novels. I would have eventually gotten there, but it would have been much, much harder.
Yes, there have been many frustrations since then, trying to work in my original novels, endless delays with editors (more 2-year waits, now on option books), no luck with several novels written in the "gap" time. But just knowing someone believed in me -- enough to ask me to come play in her world -- still shines as a beacon of hope in my life.
Now I edit as well as write, and occasionally get to be the beacon myself.
