每个人都有两次生命，第二次开始于他意识到自己只有一次生命的时候。
Every man has two lives, and the second starts when he realizes he has just one.
当思想掌握了群众，它就成为一种物质力量。
"Memory is a kind of accomplishment, a sort of renewal even."
Innovation comes from saying no to a thousand things to focus on the few that really matter.
——赠宋庆龄题词，1922年
当你认为你理解了一个问题时，你就停止思考它了。
"A good book is a magic gateway into a wider world of wonder, of joy, of meaning."
我认为对自己有幽默感是很重要的。
