August 31, the scorching heat was nearing its end.
Li Zheng's systematic foundation in aerospace studies had finally reached a point where he could modestly claim some understanding.
Gladwell had proposed the "10,000 hours" rule in his book "Outliers"—
"The reason people see geniuses as extraordinary is not because they have supernatural talents."
"Rather, it's because of their continuous and relentless effort."
"10,000 hours of practice is a necessary condition for anyone to go from ordinary to extraordinary."
Li Zheng felt ashamed.
In these 21 days,
he had only put in 2,000 hours.
He was merely one-fifth of the way toward becoming extraordinary.
