Death of a Salesman
(Trigger warning: suicide)
I once explained to a small group my ideas for selling an odd mismatched item. At the end of the discussion, in which I shared a rather off-the-wall approach that actually HAS worked before, one of the people asked me if I could sell ice to the Eskimos.
“No,” I said, “but I would sell them a freezer to store it in.”
Because that is what they need.
