有时逃避的最好方式就是面对你正在逃避的东西。

当我们真正关注任何事物时，即使是一片草叶，它也会变成一个神秘、令人敬畏、无法形容的壮丽世界。

《诗经》上说”必须选择所使用的染料,必须谨慎地来浸染”,就是这个意思。

出自北齐·颜之推《颜氏家训·勉学》。不得，不能、不可。雌黄，矿物名，可作颜料，古代用以涂改文字，后引申为信口更改、随便乱说。没有读够一定数量的书，对前人的见解没有彻底了解，是不能随便乱下结论、乱发议论的。书要多读、话要谨慎；应当谦虚向学，不可妄自尊大。

I have a vivid memory of what happened， and it was not what I expected. I expected to be applauded for my cleverness and arithmetic skills. "Jeff， you're so smart. You had to have made some tricky estimates， figure out the number of minutes in a year and do some division." That's not what happened. Instead， my grandmother burst into tears. I sat in the backseat and did not know what to do. While my grandmother sat crying， my grandfather， who had been driving in silence， pulled over onto the shoulder of the highway. He got out of the car and came around and opened my door and waited for me to follow. Was I in trouble？ My grandfather was a highly intelligent， quiet man. He had never said a harsh word to me， and maybe this was to be the first time？ Or maybe he would ask that I get back in the car and apologize to my grandmother. I had no experience in this realm with my grandparents and no way to gauge what the consequences might be. We stopped beside the trailer. My grandfather looked at me， and after a bit of silence， he gently and calmly said， "Jeff， one day you'll understand that it's harder to be kind than clever."
