Deliberate Practice: the 10 000 hour rule

Gladwell repeatedly mentions the "10,000-Hour Rule", claiming that the key to achieving world-class expertise in any skill, is, to a large extent, a matter of practising the correct way, for a total of around 10,000 hours


  • 2 hours per day
  • 10 hours per week
  • 520 hours per year
  • 5200 hours in 10 year(s)
  • 10000 hour-rule

    You did not reach the 10.000 hours of deliberate practice that would make you great. You could try to:

  • do more per day: 3.8 hours/day
  • do it for longer: 19.2 years
