Unrelated news: rejection is hard. It's hard when you get a form rejection, it's hard when you don't get a rejection and have to follow up to get an answer, it's even hard when you get a nice, personalized "almost, but not quite." My record is four rejections in one day; I'm sure some of you have had even more discouraging high scores. All told, I've probably received hundreds of rejections in the short time I've been submitting work for publication, and again, I'm sure that those of you who have been looking for represenation for years (whether or not you've since found an agent) have had more than your share of the same.
Keep at it.
Because here's the thing: if you're truly horrible, agents will auto-reject you faster than you can say "form letter." If after thirty years and a million rejections you still haven't gotten beyond the query stage, it may be time to consider a new direction (hint: you're either a terrible writer or simply unsalable). If you're pretty good, you'll start getting personalized rejections and requests for partials, and so long as you keep reading and writing and learning, you're going to get better. And if you're good and you know it, keep on keepin' on: all it takes is time.
Sometimes more time and sometimes less, but if you're getting personalized rejections from literary magazines for your short stories, or three or four agents have told you they loved the writing but the project wasn't for them, or you've been a finalist in a couple of contests, you're at least on the right track. Do your research, keep submitting, and don't get bogged down by rejection. Everyone who has succeeded has been rejected at some point, and even the best and most successful authors probably, all told, have far more rejections to their names than acceptances.
You need a thick skin to work in this industry. If you want to be a writer, you'd better get working on it now.
