成功不是幸福的关键。幸福是成功的关键。如果你热爱你所做的事情，你就会成功。

The deepest need of man is the need to overcome his separateness, to leave the prison of his aloneness.

只为自己活着的人，不值得活在世上。

诚恳：不要恶意欺骗人，思想纯洁公正，讲话也是如此。

"The poem is not a closed field, but an open one."

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."
