And you know, along the way in this journey of discovery, I learned a lot. I learned a lot about science. But I also learned a lot about leadership. Now you think director has got to be a leader, leader of, captain of the ship, and all that sort of thing.

I didn't really learn about leadership until I did these expeditions. Because I had to, at a certain point, say, "What am I doing out here? Why am I doing this? What do I get out of it?" We don't make money at these damn shows. We barely break even. There is no fame in it. People sort of think I went away between "Titanic" and "Avatar" and was buffing my nails someplace, sitting at the beach. Made all these films, made all these documentary films for a very limited audience.

No fame, no glory, no money. What are you doing? You're doing it for the task itself, for the challenge -- and the ocean is the most challenging environment there is, for the thrill of discovery, and for that strange bond that happens when a small group of people form a tightly knit team. Because we would do these things with 10-12 people working for years at a time. Sometimes at sea for 2-3 months at a time.

And in that bond, you realize that the most important thing is the respect that you have for them and that they have for you, that you've done a task that you can't explain to someone else. When you come back to the shore and you say, "We had to do this, and the fiber optic, and the attentuation, and the this and that, all the technology of it, and the difficulty, the human performance aspects of working at sea, you can't explain it to people. It's that thing that maybe cops have, or people in combat that have gone through something together and they know they can never explain it. Creates a bond, creates a bond of respect.

So, when I came back to make my next movie, which was "Avatar," I tried to apply that same principle of leadership which is that you respect your team, and you earn their respect in return. And it really changed the dynamic. So, here I was again with a small team, in uncharted territory doing "Avatar," coming up with new technology that didn't exist before. Tremendously exciting. Tremendously challenging. And we became a family, over a four and half year period. And it completely changed how I do movies. So, people have commented on how, well, you know, you brought back the ocean organisms and put them on the planet of Pandora. To me it was more of a fundamental way of doing business, the process itself, that changed as a result of that.

So, what can we synthesize out of all this? You know, what are the lessons learned? Well, I think number one is curiosity. It's the most powerful thing you own. Imagination is a force that can actually manifest a reality. And the respect of your team is more important than all the laurels in the world. I have young film makers come up to me and say, "Give me some advice for doing this." And I say, "Don't put limitations on yourself. Other people will do that for you, don't do it to yourself, don't bet against yourself. And take risks."

NASA has this phrase that they like: "Failure is not an option." But failure has to be an option in art and in exploration, because it's a leap of faith. And no important endeavor that required innovation was done without risk. You have to be willing to take those risks. So, that's the thought I would leave you with, is that in whatever you're doing, failure is an option, but fear is not. Thank you.
