Something I've learned in the last few months is that other writers often know better than I do. I have an awesome group of writers I turn to frequently to get ideas, opinions, feedback and a good kick in the pants. They are incredible and they each have different things they are better at than anyone else I know.
If I want to work on a certain kind of scene - I talk to one. If I want to work on dialogue - it's a different one. Scenery is yet another and so on.
I used to implement every single suggestion any of them gave me. Sometimes they were fabulous, sometimes they contradicted each other, sometimes I just got befuddled.
This has caused me to rethink the way I edit and take feedback. Every suggestion I get, I think about, mull over and decide whether I agree with it. Often I do, occasionally I don't. I go with my own instincts about the edit no matter what.
Here is my advice for you. Surround yourself with people who have strengths where you have weaknesses. Help them and let them help you. Don't be afraid to rely on their expertise and assistance.
But at the end of the day, it is more important to trust in yourself. You are the defender, protector, promoter and perfecter of your own story. Don't shirk your responsibilities to your characters. Believe in them and in your own ability to tell their story.
Also, make sure you have toothpicks handy to prop your eyes open for those late night edits. ;)
