I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit.

译文：一句话不小心就会招致祸患，一件事不小心就会玷污名节。赏析：口无遮拦的人迟早会给自己带来祸患，行为不检点之人更会玷污自己的名节。我们的一言一行不仅关乎名节，更关乎性命。

宇宙不仅比我们想象的更奇怪，它比我们能够想象的还要奇怪。

My past doesn't define me, it's just part of my story.
