"It takes courage to step into the unknown. It is just as Carlos Castaneda said in The Yaqui Way of Knowledge: "The first enemy of a man of knowledge, a real pursuer after the truth, is fear. Fear confronts us all of the time. It never goes away. It always comes back. But you can't begin to grow until you get over the fear. How do you get people to recognize that they are doing what they are doing because of a fear of the future, a fear of unpredictability?"
