Many of you here have probably heard of the 10,000 hours rule.
It's the idea that to become great in anything takes 10,000 hours of focused practice, so you'd better get started as early as possible.
The poster child for this story is Tiger Woods.
His father famously gave him a putter when he was seven months old.
Fast-forward to the age of 21, he's the greatest golfer in the world.
It's the quintessential 10,000 hours story.
Another is that of the three Polgar sisters, whose father decided to teach them chess in a very technical manner from a very early age.
Two of his daughters went on to become grandmaster chess players.
I got curious.
If this 10,000 hours rule is correct, then we should see that elite athletes get a head start in so-called deliberate practice.
