The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world-class expert - in anything. In study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, and what have you, this number comes up again and again…no one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.

We're making more and more decisions every day. I think a lot of us feel overloaded by the process.

I agree with the sentiment that it's probably more dangerous to believe some things that aren't so than to not believe something - you know, to believe in a lie.

In order to be a world-class expert in anything, be it audiology, drama, music, art, gymnastics, whatever, one needs to have a minimum of 10,000 hours of practice. Unfortunately, it doesn't mean that if you put in 10,000 hours that you will become an expert, but there aren't any cases where someone has achieved world-class mastery without it! So the time spent at the activity is indeed the most important and influential factor.
