“What is an obsession? It is a form of programming that has gotten completely out of hand. Religious fanatics are a prime example, as are those people who become enveloped in a political concept. Most of man’s progress has come about as a result of obsessions. The Wright brothers were not just tinkerers with an idea; their idea swallowed them up. Most leaders are obsessed with power or possessed by egos so large their only concern is their place in history. I have known writers obsessed with a single subject. Like Bobby Fischer and chess, anything and everything outside their subject seems meaningless. Any art form—music, painting, dance—is done best by those who are completely possessed by it. Such possession often borders on madness. This world would be a sorry place without such madmen.”
