As he sees it, "for a true mountain climber, only the heights and the solitude matter. Being faced with an unclimbable crag, or caught in a raging storm, has made me very aware of how small and weak I am, and of how little I know of this vast world."
他常說：「一個真正的登山家，只擁有『高』與『孤寂』是不夠的；當我面對無法走近一步的大斷崖、迫使我動彈不得的大風雨，都更覺得自身的渺小，及未知世界的廣闊。」所以，迂迴於千百轉折山徑的同時，他也勤於涉獵登山有關的知識。
