A study by K. Anders Ericsson, which looked at musical prodigies, found the common denominator for mastery and success: 10,000 hours of practice. “The emerging picture from such studies,” says neurologist Daniel Levitin, “is that 10,000 hours of practice is required to achieve the level of mastery associated with being a world-class expert—in anything.” 10,000 hours is the equivalent of 20 hours a week for 10 years.
