When we understand knowledge-based systems, it will be as before -- except our fingertips will have been singed.

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。

I love to think of nature as an unlimited broadcasting station, through which God speaks to us every hour, if we will only tune in.

Challenges are opportunities in disguise.
