Good Enough:

Thunderheart. It is the one amazing piece evidence of her self. Her very own self, sung in the only voice she had, a voice that she somehow decided was good enough.... It is as if she came up from hell to make this one thing, a record, and then she went back.
-Miranda July, I Kiss a Door

It's so great when someone decides that their work is good enough. It's as if they suddenly realized they like it. For the first time, they really see it. They stop asking what someone else thinks, because it doesn't matter. And what brings them to this stunning conclusion?

Desperation.Unending pain. Something like that. She probably did come up from hell to make that one thing.
