I promised myself I'd never do this, but hey, I've promised myself a lot of things and I've found that I'm simply untrustworthy, so I'd just better learn to live with myself.
If you are a writer, you must read, must follow, The Rejectionist:
THERE'S NO CRYING IN PUBLISHING. Go out there with your fabulous selves, and own that shit. OWN IT. LOVE YOURSELF. Own how awesome you are, and how brave, every last one of you. Fuck a bunch of form letters. You're a fucking WRITER.
And don't let me, or any other editor, tell you differently.
