"I think that it’s easy to give it away—give the definition of success away. Empower other people in determining whether you have talent. The catch-22 is that the more you do that the less you’ll be able to write. That’s the hard part – writing is all about the preservation of your own voice. So if you give that voice away by guessing what you think and you think and you think as you go, you’ll have less to say and then it’ll go away completely!"
