When you've spent thirty years entering rooms filled with strangers you feel less pressure than when you've had only half that number of years of experience. You know what the room and the people in it probably hold for you and you go looking for it. If it's not there, you sense it earlier and leave to go about your business. You just know more about what is, what isn't, and how little time there is to learn the difference.
Dan Simmons, Hyperion
