I think it’s useful for all us writers to remember no one work pleases everyone, and you can’t make anyone like it if they don’t, and you can’t keep them from telling other people what they think of it, even if they hate it… and that’s fine. Learn to deal with it. Otherwise it doesn’t matter how much success or praise or satisfaction you earn through your writing, you’ll still obsess over those one-star reviews and it will eat away at your joy. That’s no way to live.
So: own your one star reviews, don’t let them own you. And once you own them, let ‘em go. You’ll feel better, and you’ll worry less about them going forward. Try it for yourself. You’ll see.
