We think of precociousness as an early form of adult achievement, and, according to Gladwell, that concept is much of the problem. “What a gifted child is, in many ways, is a gifted learner. And what a gifted adult is, is a gifted doer. And those are quite separate domains of achievement.”

To be a prodigy in music, for example, is to be a mimic, to reproduce what you hear from grown-up musicians. Yet only rarely, according to Gladwell, do child musical prodigies manage to make the necessary transition from mimicry to creating a style of their own. The “prodigy midlife crisis,” as it has been called, proves fatal to all but a handful would-be Mozarts. “Precociousness, in other words, is not necessarily or always a prelude to adult achievement. Sometimes it’s just its own little discrete state.” —Eric Wargo —The Myth of Prodigy and Why it Matters (Association for Psychological Science)
