I'm sure most of you have heard this idea--that many successful people are not necessarily more talented than the rest of us, but have put in hours and hours of practice to master their specialty. The idea is it takes about 10,000 hours, or approximately several hours a day for 10 years. (If you haven't, see Malcolm Gladwell's book, Outliers: The Story of Success
http://www.amazon.com/Outliers-Story...9868915&sr=8-1).
So, I was wondering--have any of you actually practiced something this long and mastered? Is there anything you'd want to practice for mastery?
