You might be thinking of Barbaro the horse. Sad as that is, I'm not mourning about that.
See last night, I completed a gigantic set of edits for Isle of Swords. I had to cut a lot. Like 40 pages a lot. That hurts. Goodbye 1/6 of the book. I understand why we're cutting. In some cases I totally agree that it's necessary. But no mater what. It hurts.
Every person feels a sting when something they've done is criticized. Creative types feel it worse, IMHO. Maybe it's because we are CREATIVE people, and that is how we define ourselves. We get our self image completely entangled with the products we create. When someone wants to change it, BANG, hit to our self image. When someone wants to cut it, OUCH, it's a part of ourselves being sheered away.
For the Christian writer, maybe this is one of His many tools to help us to intertwine ourself image in the correct place--with Him. How does God see us? What do you think God thinks of you? If we take Him at His word, he sees us as His children, loved, worth dying for. Y'know, somehow, in light of Him, the cuts don't hurt so much anymore.
