Yo, this is a sentiment that really helps me when I sit down and write stuff.

Write like a reader.

You know what you like in works of fiction, so focus on that. Likewise, you know what you don't like. Fuck what anyone else likes or doesn't. Yes, you're writing for a competition where the judges decide who posted the better work; if you let that get you down, you'll never improve.

Feedback's important; not as important as the joy YOU get out of it.
