Rejection is part of the process. I know this, and I try not to take any of them personally. Each one does make me a little sad, but on the other hand it is far better than not knowing at all. The “no response means no” tactic that many agents take is understandable given the volume they receive, but infuriating being on the other end. I would honestly rather get an email saying “Fuck off” than months of empty silence before I write that query off as a “no.”
Occasionally there are the odd success stories in various online communities where after 100+ queries and various forms of rejection, a determined writer makes that pivotal step towards their dreams and snags an agent. There are also the little bits here and there where a fact about a famous author being repeatedly rejected, like Stephen King’s dozens of rejections for “Carrie.” These are the things that help make it easier to keep trudging on. They help take the sting out of it, because the means I’m one rejection closer to “yes.”
Writing is something I already do for free, regardless of whether anyone ever reads it. I have several finished books that I have no intention of ever publishing. I have dozens of ideas for things to write, and several different works-in-progress. That being said, being a professional author is my dream. If that dream takes several years and a few hundred rejections, then so be it. Until then, I’ll just have to keep spreading the word.
