The 10,000 Hour Rule,” sometimes called “The Ten Year Rule.”

Thomas Edison was fond of saying that genius is 99% perspiration and 1% inspiration, but all of the recent research suggests that “genius” is 1 percent inspiration, 29 percent good instruction, mentoring, and encouragement, and 70 percent perspiration. In other words, geniuses (people who are highly successful at what they do)
are made, not born.

Studies of what makes some children more successful as grownups than others (and considered “geniuses” at what they do) have come up with this rule to predict future achievement.
