And as for "going through rough times to come to creative moments"...

You know, I think that allowing somebody, one mere person to believe that he or she is like, the vessel, you know, like the font and the essence and the source of all divine, creative, unknowable, eternal mystery is just a smidge too much responsibility to put on one fragile, human psyche. It's like asking somebody to swallow the sun. It just completely warps and distorts egos, and it creates all these unmanageable expectations about performance. And I think the pressure of that has been killing off our artists for the last 500 years.
