我相信伟大的教师就是伟大的艺术家，而且这样的艺术家和其他任何伟大的艺术家一样稀少。教学甚至可能是最伟大的艺术，因为它的媒介是人的思想和精神。
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.
I'm not trying to be cool. I'm just being myself.
很多时候，我们都需要面对选择。如果都有好处，就要取其中好处最大的；如果都有害处，就取其中害处最小的。
The mind of the wise is an open book.
I'm not here to fit in, I'm here to stand out.
