"And human instinct is ancient and reliable, utterly mysterious and possibly capable of great genius. I believe that refined, fluent instincts are a person's most valuable asset. My own instincts have repeatedly guided me against the grain of logic and probability. When I have trusted and followed their direction, they have never been wrong. I don't know how or why. But I know that every significant experience-positive or negative-sharpens them and makes them more accurate."
