"And where would be the fun in making something you knew was going towork?"

"Do the stuff that only you can do. The urge, starting out, is to copy. And that's not a bad thing. Most of us only find our own voices after we've sounded like a lot of other people. But the one thing that you have nobody else has is you. Your voice, your mind, your story, your vision. So write and draw and build and play and dance and live as only you can.

The moment that you feel that, just possibly, you're walking down the street naked, exposing too much of your heart and your mind and what exists on the inside, showing too much of yourself. That's the moment you may be starting to get it right. 

The things I've done that worked the best were the things I was the least certain about, the stories where I was sure they would either work, or more likely be the kinds of embarrassing failures people would gather together and talk about until the end of time. They always had that in common; looking back at them, people explain why they were inevitable successes. While I was doing them, I had no idea. I still don't. And where would be the fun in making something you knew was going to work?

And sometimes the things I did really didn't work. There are stories of mine that have never been reprinted. Some of them never even left the home. But I learned as much from them as I did from the things that worked."
