Great post at Animation Ideas. Such important points, it's not just about being able to move things in an appealing way, there's more to being a professional animator.
As an addition to 5. Make the changes quickly and 6. Take it like a man I would stress that you shouldn't be resistant to notes. Obviously if you take it like a man/woman and make changes quickly, it's safe to assume that you're not against the fixes but again, you don't want to be the guy that goes: "Those are stupid notes, I'm not going to make those changes."
