But please let's all remember that a form rejection doesn't mean your work sucks.
It might, but honestly, I'm never going to say so.
Most often, it doesn't. If you've put a lot of thought and work into your manuscript it may have problems, but it doesn't truly suck. Quit gnawing yourself to death worrying about this. Gnawing is MY job.
Let's also remember "I was nominated for an Edgar" is nice but virtually meaningless in a query letter. There are literally hundreds of Edgar nominations; all it takes is a book and an entry form.
Even worse is "I was nominated but lost out to CJ Box" when you weren't even on the short list of finalists. That's clearly hoping I'm a total dimwit and don't know how the Edgars work.
I turn down publishable material every day for a variety of reasons; one might be the author seems like an arrogant asshat.
It's ok to BE arrogant, just work on concealing it better.
Just like it's ok to think I'm a dimwit as long as you don't actually convey that in your email.
