Lecture
A new lecture is like any new tool. We use it for a while with pleasure. Then it blisters our hands and we hate to touch it. By-and-by our hands get callous, and then we no longer have any sensitiveness about it. But if we give it up the callouses disappear; and if we meddle with it again, we miss the novelty and get the blisters.
—Oliver Wendell Holmes
