儿童开始对自己实践那些他人曾经对他实践过的相同行为形式。
Every problem in mathematics is a puzzle waiting to be solved, and the joy is in the solving.
Every book is a journey, and every journey changes us.
We should measure success by outcomes, not just inputs.
与他人说话时,要留有余地,别把心里想说的全部讲出来;画虎的形态很简单,但画出骨骼却很难;熟悉人的面貌很容易,但真正了解一个人的内心却很难。
环境是我们所有人相遇的地方,是我们共同关心的地方,是我们所有人共享的东西。
