Why 10,000?

 

In the past, to perfect one’s techniques, one must practise it for 10,000 times, Bruce Lee once said. To be excellent in anything, one must constantly practise it for 10,000 hours, said Malcolm Gladwell in his book. To be healthy, one must achieve 10,000 steps daily, said someone.

Now, I discover there is no real scientific explanation for this ‘magic’ number. It’s plucked from the air and someone just turned it into a gimmick or something new to make money! ☹
