Maynard, Jonny, Colin, and Sheila 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. Maynard cannot keep a steady beat when on bass or drums, Colin sounds terrible on everything except the bass, nobody except Jonny can remember all the chords on guitar, and even Sheila'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
