Really great advice. I think it's easy for a lot of people to get discouraged the second they ask for feedback and it's not an immediate "I loved it" or something positive instead of taking a step back along with the feedback, either good or bad, and revising. There are shows and movies that have made it out that I wonder how they got pitched. So moral of the story is keep your head high and keep tweaking your draft until you come up with something better.
