Some children in this forum are genius. They are great in every aspect. But for the non-genius children, well balanced education is desirable. 数学 is overrated. Soft skills are more valuable at work. Motivation, characters, etc are much more important.
If our children spend most time doing math, they would become the "experts", not the CEO, not even CTO。Hopefully our next generation can stand on our shoulders, and go beyond the status of "experts".
