I love the moment when a new metaphor makes a hard concept suddenly clear. For me, teaching economics, the search for the perfect example is like the hunt for a perfect seashell on a beach with rough waves. Most shells are flawed, but I choose a handful of the best and carry those with me. Still, I'm watching, ready to cast aside a former favorite to make room for something closer to perfection.
