Neil Gaiman's keynote address at the University of the Arts in Philadelphia is making me happy right now. It's the kind of message we should all be following (whether we're artists or otherwise).
"Someone asked me recently how to do something she thought was going to be difficult, in this case recording an audio book, and I suggested she pretend that she was someone who could do it. Not pretend to do it, but pretend she was someone who could. She put up a notice to this effect on the studio wall, and she said it helped.
So be wise, because the world needs more wisdom, and if you cannot be wise, pretend to be someone who is wise, and then just behave like they would.
And now go, and make interesting mistakes, make amazing mistakes, make glorious and fantastic mistakes. Break rules. Leave the world more interesting for your being here. Make good art."
