It's sad, but true. Your story won't come out perfect the first time through. You're going to have to revise. You're going to have to get critiques. You're going to have to watch others tear your baby to shreds. And you're going to need some Writer's Intuition to guide you here too. Because not all revisions are created equal. Not every suggestion from your crit partners or beta readers is going to be good for your story, no matter how good of critiquers they are.
It is hard to get critiqued. I know that. And you shouldn't just dismiss anyone's suggestions out of hand. (Well, maybe some you can reject out of hand. Like I once got a critique that said, Your main character should be an energy being instead of flesh and blood. Um, okay.) But in general you should at least consider all the suggestions made. Then use your intuition to know which to use and which to ignore.
My rule of thumb is that any suggestions that make me excited to make changes are good suggestions. Those that don't, just aren't right for the story. Just remember that it 's your story and no one else's. Only you know what will make it truly shine. Your Writer's Intuition will show you the way.
