More on practice

You can become a world class chess player with an IQ of 100. (120 = average college student) if you just get enough study and practice.

In the Ecole system, those who reach the highest grade = those who practice the most.  There are no low practice, high talent exceptions.

Kimura, the dominant martial artist of his generation, also practiced at least 20% more than the next closest competitor. To become world class you don't even need average levels of talent or ability.  Within rough parameters, it is a matter of practice.
