““There are times when I sit at the center of the world, and when I know that I can reach out to any of the programs my good wife has written for me and pull back any fact, absorb any explanation or command any event. There are also times when I sit with a full console and a head full of burning questions and learn nothing, because I do not know what to ask. And there are times when I am so full of learning and being and doing that the moments zip past and the days are packed, and other times when I am floating in slack water beside a current, and the world is sliding speedily by.””
