So it's usually not until you are in adolescence, sometimes late adolescence, and sometimes early adulthood, that you want to get better at something in a skill development kind of way.

And so that's when you need usually a coach.

That's when you need to do, you've heard of 10,000 hours of deliberate practice.

I have, but for the person who's listening who doesn't know the 10,000 hour rule, just

Explain it back of the hand here.

I cannot tell you how excited I am to tell you about deliberate practice, the 10,000-hour rule, because I think so many people have heard it.

Anders Ericsson was a truly great cognitive scientist.

He studied Sudoku players who were at the top of their game.

He studied chess masters, grandmaster chess players.

He studied prima ballerinas.

He was the world expert on world experts.

And in one of his early studies, he found that the very best violinists at a music academy in Germany had about 10,000 hours of a certain high quality practice that he later called deliberate practice.

The next group at this music academy, they weren't as good.

They had something like 7,500 hours.

And then maybe the next group was like 5,000 hours.

There were differences in the quantity of practice.

And it became this very popular term that you got to do 10,000 hours of practice if you want to become great at what you do.
