We cannot predict with accuracy who will become élite in a given field, but we know that genes and environment matter and that we all have different natural peaks that we can reach through application and training. Saying that training is everything may be tempting, but it’s wrong. “One of the criticisms people direct at us is that we’re killing people’s dreams,” Hambrick says. “But I think in fact it’s the contrary: the more we can know about the origins of expertise, including training but everything else, the more we can help people be their best selves.” Perhaps it’s just enough to know that no matter how many hours I spend in the pool, I won’t be Katie Ledecky. And I’m pretty sure I’m not going to become Brad Mehldau, either, even if I get a better teacher."
