The past is a story we tell ourselves.

We begin with the hypothesis that any subject can be taught effectively in some intellectually honest form to any child at any stage of development.

译文：什么人可以称得上享福之人呢，当然是能读书且从中受益的人；什么人可以称得上创家立业的人呢，当然是能够教育出子孙的人。赏析：天下第一好事就是能读书，能读书说明思维活跃，头脑清晰，身体健康，而书中的道理也能从中获得。任何事业上的成功都弥补不了教育孩子失败的遗憾。身为父母，最大的成功，应该是教育出一个温暖有爱，品行端正，身心健康的孩子。
