You are not someone else’s opinion of you.

"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：经常想到这个世上还有人的处境不如我，还有人的命运不如我，就该知足感恩了；经常想到有人的德行操守超过我，有人的学问超过我，就该感到惭愧而发愤努力了。赏析：人的欲望是无穷的，也是难以满足的。很少有人做到知足常乐。人总是喜欢和其他人对比物质方面的东西，别人有的，也希望自己有。而学问，德行，却很少有人去反躬自省。
