Well, I would say, reading is some kind of essential prerequisite to everything you do. Whether you are a scientist or a filmmaker, or just a normal human being working in a more “normal” profession. I cannot argue much about it. Read, read, read, read, read. The other side, traveling on foot, nobody does it and what I said will disappear into thin air any moment from now. Traveling on foot has actually given me insight into the world itself. The world reveals itself to one who travel on foot. I can give you one example, you start to understand the heart of men. I was, for a film, at the Johnson Space Center and had to take to five astronauts who had done a space mission in a space shuttle. I wanted to persuade them to be extras in the film in a very strange way. They were sitting in a semi circle when I was taken in and my heart sank that I didn’t know “what should I say? what should I do?” I looked around and looked into their faces and all of a sudden I had the feeling, I understand these people. I understand the heart of these men and these women. I said “since I was a child, when I learned how to milk a cow with my own hands, I can tell that since I’ve traveled on foot and in the meadow first you milk a cow to have something to drink. I know by looking at faces, who is able to milk a cow.” I looked at the pilot and said “you sir!” and he burst out in smiles and says “yes, I can milk a cow.” Somehow when you make films, you understand the heart of men. In a way you cannot learn it, the world has to teach you. The world does it in it’s most intense and deepest way when you when you encounter it by traveling on foot.
I’d like to add that when I travel by foot, I don’t do it as a backpacker where you take all your household items with you, your tent, your sleeping bag, your cooking utensils. I travel without any luggage and I do not travel, let’s say, the specific trail 2000 miles which is marked. I do traveling for very intense quests in my life. I do that on foot.
