10,000hrs= expert doing...?

Am reading this academic treatise on craftsmanship..the history and politics of it, cognitive aspects of becoming an expert, etc. Looks like it's been proven or at least debated in psychology that to become a true expert at anything, is to practice that craft/sport/endeavour/profession is approx. 10,000 hrs. Which translates approx. practicing something 3 hrs. per day, EVERYDAY for 10 yrs....or 7 yrs. of apprenticework for a goldsmith.

Would you consider yourself 'expert' in cycling or what? There are different types of cycling of course.. :p

Guess becoming expert as a parent counts all those sleepless hrs. to compress that learning in less than 7 yrs.? :rolleyes:

Or did you truly feel equipped with real expertise in your profession/job after 5 yrs.? (approx. 2,000 work hrs. per yr.) My dearie argues (and I agree), a real expert in one's field may be after 10 years in the profession, preferably practicing a breadth of tasks/responsibilities.

Anything that is cognitively complex seems like it requires at least 10,000 hours. ... It's deliberate practice, so it's focused, determined, in environments where there's feedback, where there's a chance to really learn from mistakes. What's fascinating about this notion that expertise arises only after 10,000 hours of deliberate practice is that it seems to apply incredibly broadly to an astonishing array of different professions - from playing chess to writing classical music to being a brain surgeon to playing hockey.
