> And things that require a lot less than 10,000 hours aren't very impressive (driving, for example) because lots of people learn to do them.
I just guesstimated that I spent maybe 7,500 hours (over 3.5 years) driving around in a taxi. Towards the end of that period I started to notice things that the other cars on the road would likely do, and point this out to my passengers. "See that car? it's going to change lanes and that other guy is going to have to slam on his brakes..."
Just the other day I was driving with my mother. Our light turned green, but I saw that the car in the cross traffic couldn't see that his light had turned red (on account of the sunset). I waited, and watched as he slammed on his brakes. (Not especially impressive, just recent.)
There's something to putting in time on any activity. With regards to this article postulating that "10,000 hours rule" doesn't matter... I think the relevant saying is not "practice makes perfect", but "perfect practice makes perfect". If you spend 10,000 practicing something wrong it won't be as helpful as 1,000 hours practicing it right.
