永远不要停止学习。当你认为自己无所不知的那一刻，就是你停止成长的那一刻。

"The past is always present in our lives, shaping who we are and how we see the world."

生活中唯一的残疾是坏态度。

The universe would look to a two-dimensional creature who spend its life moving on the service of what turned out to be a globe， it could travel for millions of years and would always return to its starting point， it would never be conscious of what was above it or beneath it.

对知识的追求是无止境的，而这正是它令人兴奋的地方。

You may think I’m small, but I have a universe inside my mind.

幸福来自内心。
