We're not going to tell you someone is waiting for you. Maybe no one is. Maybe this text sits at zero readers for six months. Write it anyway. That's it. There's no moral.
Novelist at the top. Fanfiction at the bottom. Pure worldbuilder nowhere, because nobody knows where to shelve them. We built LATRAME without floors. Not out of kindness. Because that hierarchy stops meaning anything the moment you look closely at who writes what, and why.
A rejection never says "this isn't good." It says "not this reader." Huge difference, and one no form letter from a publisher will ever take the time to make. Neither will the algorithms, by the way. They don't even bother sending the letter.
