Belated "between your ears". And sometimes that's what beta-reading is for. It's just happened to me; my beta picked up a load of the places I didn't feel good about myself, but at the same time that helped me focus on them and make them better (meaning I CAN make them better) without flailing around helplessly.

By the way, I also recently discovered Stuff, but didn't get around to commenting... and, hey, if it helps I saw the warts and I think you're better than that now, so it's not all bad. I'm kind of admiring you from the distance; I'm one of those people most of your stuff isn't for, but at the same time you're one of those people who made me go "Oh, there can be so much more done with Narnia!", and this is a belated thank you for expanding my own horizons like that.
