The 10,000-Hour Myth and What to Actually Tell Kids About Practice
The popular version of the 10,000-hour rule says that anyone can master anything with enough practice. But Anders Ericsson, the researcher behind the original study, spent years correcting this oversimplification. His actual finding: it is not practice that leads to mastery. It is deliberate practice — focused, effortful work on specific weaknesses with feedback.
A child who practices piano for an hour by playing songs they already know is not doing deliberate practice. A child who spends 20 minutes on the part they keep getting wrong, with a teacher’s feedback, is.
The Distinction
Teaching Deliberate Practice
Identify the hard part, then practice that. "Which part of the math problem keeps tripping you up? Let us do five more of just that part." This is counterintuitive for kids (and adults) who prefer to practice what they are already good at.
Keep sessions short and focused. 20 minutes of deliberate practice beats 60 minutes of unfocused repetition. The brain needs intensity, not just duration. Shorter sessions also reduce frustration.
Provide or seek specific feedback. "Good job" is not feedback. "You got the tens digit right every time but mixed up the ones digit" is feedback. Specificity is what turns repetition into learning.
"The most effective practice is not the most practice. It is the most targeted practice."
— Anders Ericsson, Peak: Secrets from the New Science of Expertise (2016)Stop telling your kids that practice makes perfect. Start showing them that the right kind of practice makes progress. That is a more honest and more useful message.
