Why do all of these examples always focus on physical tasks that are obviously improved by practice. Playing a musical instrument like piano or playing a physical sport like tennis takes hand eye coordination, strength, agility and endurance. These examples are so horribly one-sided. Of course practicing a repetitive, manual example for 16 hours a day will make you better at it. That's called motor control skills and luckily for these mothers it has nothing to do with interest or liking what you're doing. Yes you can force someone to develop better motor control skills. But please don't start conflating that with "life skills" and "determination". Training your kid to be the best at fine motor control and manual dexterity is not exactly the way to be successful in the 21st century. They can learn that from video games. And don't call this Chinese parenting, my Russian-Jewish mother made me study in very similar ways when I was younger. Fortunately, for me she realized that rote memorization is not the linchpin of a successful career, but at best a tiny foundation stone in your studies.
