人心是天渊。心之本体，无所不该，原是一个天。只为私欲障碍，则天之本体失了。心之理无穷尽，原是一个渊。只为私欲窒塞，则渊之本体失了。
译文：人心就像天空和深渊。心的本体，无所不包，原本就是一个天。只是因为被私欲所阻碍，那么天的本体就丧失了。心中的道理无穷无尽，原本就是一个深渊。只是因为被私欲堵塞，那么深渊的本体就丧失了。
Never underestimate the power of perseverance.
The only thing that matters is what you believe in yourself.
"The true value of science lies in its ability to change our perspective."
The ultimate measure of a man is not where he stands in moments of comfort and convenience， but where he stands at times of challenge and controversy.
