There are many people that spend years writing and perfecting their novel, short story, or poem for it never to be seen by another human being, but will maybe read it aloud to their cat on valentines day if the feline in question promises to poop in the goddamn sandbox.
These people (that we'll call Bob) got a rejection notice on the first thing they ever sent to a publisher, and never tried again, thinking to themselves "Well, if editor A thinks my stuff is crap, I guess my Mom was right about my writing, and I should consider truck driving school."
Here's the thing... Just because Editor A twisted his mustache and stomped on Bob's dreams, it doesn't mean Editor B will. In fact, Editor B will run over those dreams with a steamroller. What Bob doesn't see is that it may take all the way through editor gamma (Bob ran out of english alphabet letters and had to go to greek) before Bob gets that validation of "yes, we'd like to see the full manuscript"
Rejection is part of the job, kids. Be ready to hear lots of bad stuff about your work before you hit that editor that "gets" where you were coming from with the drag queens exploring the final frontier, because when you find that editor, it's soooo worth it.
