> It doesn't take 10,000 hours to become a master striker in football Wrong. 25 hrs / week * 50 weeks / year = 1250 hours. So 8 years of football = 10k hours

> It doesn't take 10,000 hours to become a master striker in football Wrong. 25 hrs / week * 50 weeks / year = 1250 hours. So 8 years of football = 10k hours. Most pro strikers have been playing since they were 8y/o; by 16y/o, they have acquired their 10k hours. I think it's the other way around - 10k hours doesn't really get you to true mastery - it's more like 50-100k hours. As Mas Oyama, founder of Kyokushin Karate, once said: "After 1000 days (=10k hours), you are a beginner. After 10,000 days (=100k hours), you are a master."
