"I don't want to achieve immortality through my work - I want to achieve it by not dying."

         "Here is a test to see if your mission on earth is finished. If you are alive, it isn't."

        "It is well to remember that the entire universe, with one trifling exception, is composed of others."

        "You see things and you say 'Why?' I dream things that never were and say 'Why not?'"
