"The experience of climbing Kilimanjaro affected me so powerfully that, for a long time afterward, if I caught myself saying, "I'm not a person who likes to do that activity, eat that food, listen to that music," I would automatically go out and do what I imagined I didn't like. Generally I found I was wrong about myself - I liked what I thought I wouldn't like. And even if I didn't like the particular experience, I learned I liked having new experiences."
