A man of knowledge lives by acting, not by thinking about acting, nor by thinking about what he will think when he has finished acting. A man of knowledge chooses a path with heart and follows it; and then he looks and rejoices and laughs; and then he sees and knows. He knows that his life will be over altogether too soon; he knows that he, as well as everybody else, is not going anywhere; he knows, because he sees , that nothing is more important than anything else.
