The 10,000 Hour Rule says no one gets to the top of their field unless they log at least 10,000 hours of practice. That’s right - 10,000 hours!
The rule has been repeated multiple times by many people.. the latest person is Malcolm Gladwell (author of Tipping Point and Blink), in his new book Outliers: The Story of Success
Other people include Peter Norvig (Director of Research, Google) on his blog in the post "Teach Yourself Programming in Ten Years" here
