The biggest meta-analysis of research to date indicates that practice does not make perfect.
The 10,000 hour rule—first proposed by a Swedish psychologist and later made famous in Malcolm Gladwell’s Outliers—states that exceptional expertise requires at least 10,000 hours of practice.
But is it true and accurate? Some say yes and some say no.
There is no magic to reaching 10,000 hours or nothing that states tada you are now an industry guru!
Authors of a new study undertook the largest literature survey on this subject to date, compiling the results of 88 scientific articles representing data from some 11,000 research participants.
It is believed based on this study that practice explains just 12 percent of skill mastery.
And the rest? Other factors like age, intelligence, talent, desire/hunger, access to proper trainers, support from others, perseverance and much more all appear to play a bigger role.
“So despite the new evidence that the 10,000 rule is bull, like the studies and articles that came before it, that message will likely fall on many deaf ears. The 10,000 hour rule seems to have entered into the common lore about success: it’s a nice idea, that hard work will actually pay off. And no peer-reviewed study has so far succeeded in toppling that catchy message.”[SOURCE](http://www.smithsonianmag.com/smart-news/10000-hour-rule-not-real-180952410/?no-ist)
