Many characteristics once believed to reflect innate talent are actually the result of intense practice extended for a minimum of 10 years. 先天的な才能を反映するとかつては信じられていたさまざまな特徴も、実は集中的な練習を少なくとも10年続けた成果なのだ。
Confirming our theoretical framework, the violinists in all groups rated practice alone as the most relevant activity for improving violin performance.

The great minds of science were not distinguished as being exceptionally brilliant as measured by standard IQ tests…What was singular was their capacity for sustained work.
