“I want to be, if I can, as sure of the world--the real world--around me as is possible. Now, you can only attain that to a certain degree, but I want the greatest degree of control. I've never involved myself in narcotics of any kind, I don't smoke, and I don't drink because that can easily just fuzz the edges of my rationality--fuzz the edges of my reasoning powers--and I want to be as aware as I possibly can. That means giving up a lot of fantasies that might be comforting in some ways, but I'm willing to give that up in order to live in an actually real world, or as close as I can get to it.”
