How do you become an expert at something, and truly master it? The answer, some will tell you, is with 10,000 hours of practice.
The so-called rule of 10,000 hours originated in a best-selling book, ‘Outliers’, by journalist, Malcolm Gladwell. He based the ideas at the core of his book on research that Anders Ericsson carried out, along with Ralf Krampe, and Clemens Tesch-Römer.
Then, he was a Professor at the University of Colorado. Now he’s at Florida State University. But here is the thing… Ericsson has been openly critical of the 10,000 hours formulation. And that offers both good news and bad for any of us who want to become world-class masters of any field.
