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

Calculation

  • 3 hours per day
  • 21 hours per week
  • 1092 hours per year
  • 10920 hours in 10 year(s)
  • 10000 hour-rule

    You have reached 10.000 hours of deliberate practice! You might even do it:

  • do less per day: 2.7 hours/day
  • do it faster: 9.2 years
