" The root of the trouble lies usually in the mistaken attitude of the beginner. Instead of looking at an easy scramble close to the ground and thinking "I could do that", he looks at some forbidding vertical wall which he knows has been climed, and feels "I could never do that". When told that an impossible-looking building is a field for climbers, he is apt to feel, like a child watching a conjurer, that there is magic in it and it is not for him. So he shies, and perhaps never makes a start. "
