Hopefully with each thing that you do you're learning something you're growing and you're pushing yourself a little harder in some way or another. So I think you'd be in real trouble if each new thing that you create didn't feel like 'Oh wow. I feel like I'm doing something a little different this time.'
I cannot consistently with self respect do other than I have namely to deliberately violate an act which seems to me to be a denial of everything which ideally and in practice I hold sacred.
