"My work to me is more like what the Native Americans say: When we walk upon the earth, we always place our feet very carefully upon the ground, because we know the faces of our future generations are looking up at us from below, and we never forget them. I think as a culture today we've forgotten them. This work is a way to help us remember them. It's a way for us not only to find meaning in our individual lives, but to extend that approach all across the planet. Because if we don't, we won't have a planet."
