Consider what Roger Federer can do with a tennis ball, or Connor McDavid with a puck. There are chess grandmasters who can play several dozen different games simultaneously--while blindfolded--and a seemingly unending supply of young musical prodigies who would have astonished aficionados a century ago. That's only partly true. On the surface, the techniques that chess players use to develop their skills seem quite different from the methods soccer players use to perfect their games, which in turn seem quite different from how pianists improve their playing. But at a deeper level, they are all variations on a single fundamental approach to learning, what Ericsson, a world-renowned researcher, has named "deliberate practice": a simple, yet powerful system for enhancing learning. Whether you want to step up your game at work or on the weekend, or help your kid achieve athletic or academic goals, Ericsson's revolutionary methods will show you how to master almost anything."
