Some things don't go the way they're planned. We often call them "mistakes." But some of the best things have come from unplanned events, miscalculations, or aberrations: the Ferrari Testarossa, the Post-It note, and even Jason Cammisa. We asked his mom. Jason was a mistake. Doesn't make him less of a Jason. And the Testarossa, despite its huge commercial success, was part of a lineage of Ferraris which was, in retrospect, compromised at its mission.
