Consider four of Aesop's fables. 1. A lion and a bear seized a lamb at the same moment and fought fiercely until they collapsed, exhausted. A fox ran in, seized the lamb, and quickly ran off. The lion and the bear watched him and said, "Just our luck, that we fought, only to serve the reward up to the fox." 2. A hound chased a rabbit but gave up after a long run. A shepherd watched and said, "The rabbit is the better runner." The Hound replied, "I only ran for dinner. He ran for his life." 3. As Patty walked to the market, her milk pail on her head, she planned what she would do with the money she earned. "I'll buy hens, and sell their eggs. Then I'll buy a new dress! Polly will be jealous, but I shall just toss my head like this." As she tossed her head back, the pail fell off, and all the milk was spilled. 4. One day a farmer found an egg of pure gold in the goose's nest. The goose laid a golden egg every morning, and the farmer soon grew rich - and greedy. Thinking he would get all the gold at once, he killed it but found no gold inside. Which fable from Aesop best illustrates the moral idea that incentive spurs effort?

Thom, Juliana, D'arcy, and Cindy are trying to form a band. They each have some basic skills on most instruments, so their current plan is for each of them to rotate among vocals, guitar, bass, and drums. After a year of practice and rehearsals the band still sounds awful. Thom cannot keep a steady beat when on bass or drums, D'arcy sounds terrible on everything except the bass, nobody except Juliana can remember all the chords on guitar, and even Cindy's own mother thinks her singing sounds like a dying cow. At their current rate, they expect it will be several years before they are good enough to land their first paid performance. None of them have enough money saved up to last that long. They all know you are taking economics and ask your advice. What would you say to them?
Have each member specialize in the role that they are best in to take advantage of benefits from specialization.
