Trust is super important in the writing process. You need to not only trust yourself–making the right decisions–but you need to trust those you give your work to critique.
We have to trust that those people are giving us good, valuable advice. But we also need to trust ourselves to make changes based on that advice that makes sense to our original vision.
If you can’t trust yourself or those giving you advice, I think you need to take a step back and figure out what you need to do to get that trust.
