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.
