Be blunt. Be cruel. Be absolutely brutal to your offspring.
Your kid lost a Sicilian Defence despite memorising some 30 moves of theory? Just call them stupid. That'll learn 'em. Not even 50% in the Aussie Juniors? Toss out all their toys and ban all the partying until the next Aussie Juniors. Then sit back and watch the trophies roll in.
Amy Chua in the Wall Street Journal:
The fact is that Chinese parents can do things that would seem unimaginable—even legally actionable—to Westerners. Chinese mothers can say to their daughters, "Hey fatty—lose some weight." By contrast, Western parents have to tiptoe around the issue, talking in terms of "health" and never ever mentioning the f-word, and their kids still end up in therapy for eating disorders and negative self-image. (I also once heard a Western father toast his adult daughter by calling her "beautiful and incredibly competent." She later told me that made her feel like garbage.)
Chinese parents can order their kids to get straight As. Western parents can only ask their kids to try their best. Chinese parents can say, "You're lazy. All your classmates are getting ahead of you." By contrast, Western parents have to struggle with their own conflicted feelings about achievement, and try to persuade themselves that they're not disappointed about how their kids turned out.
You're probably thinking that this woman's a total nutjob. But hey, she's a law professor, at Yale no less. She knows what she's talking about.
