Here's writer Neil Gaiman's graduation address to the University of the Arts Class of 2012. (Thanks and a tip of the hat to Ronk.)
Two excerpts:
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 that 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.and
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?
We're in a transitional world right now, if you're in any kind of artistic field, because the nature of distribution is changing, the models by which creators got their work out into the world, and got to keep a roof over their heads and buy sandwiches while they did that, are all changing. I've talked to people at the top of the food chain in publishing, in bookselling, in all those areas, and nobody knows what the landscape will look like two years from now, let alone a decade away. The distribution channels that people had built over the last century or so are in flux for print, for visual artists, for musicians, for creative people of all kinds.
Which is, on the one hand, intimidating, and on the other, immensely liberating. The rules, the assumptions, the now-we're supposed to's of how you get your work seen, and what you do then, are breaking down. The gatekeepers are leaving their gates. You can be as creative as you need to be to get your work seen. YouTube and the web (and whatever comes after YouTube and the web) can give you more people watching than television ever did. The old rules are crumbling and nobody knows what the new rules are.
So make up your own rules.
