Likely best to have a thick skin as, IIRC from JB's articles, you'll get a lot of rejection letters. Then again, you'll probably learn more from the beats you take from an editor than by fretting about whether or not your work will be accepted.

I always maintain that I've learned the most by taking a beating on the stand.
