做一个犹太人就是做一个见证者。

What I want to talk to you about today is the difference between gifts and choices. Cleverness is a gift， kindness is a choice. Gifts are easy -- they're given after all. Choices can be hard. You can seduce yourself with your gifts if you're not careful， and if you do， it'll probably be to the detriment of your choices.

出自北齐·颜之推《颜氏家训·教子》引谚语。教育媳妇，要趁她刚嫁到婆家之时；教育孩子，应当赶在孩提时代，教育要掌握最适宜的时间才会有效果。
