I'm wearing my first rejection as a badge of honor. I feel like I've passed through a doorway that was previously closed to me.
I have choices now. I choose to do a commercialized rewrite of my story and to bring it up to par with the expectations of a YA novel. More at stake, more romance, more conflict, more competition, just more. I have a lot of personal experiences to pull from, come to think of it. :-)
It's a whole new ballgame, baby!
