凡是做学问，必须从各个方面都理解透彻，还要更进一步深入理解内在的道理。

"Every story is a journey, and every journey changes the traveler."

You don't need a weatherman to know which way the wind blows.

We are all born mad. Some remain so.

戒酗酒，酗酒伤神；戒色欲，贪色灭精神；戒美味，美味使精神昏沉；戒过饱，过饱使精神郁闷；戒多动，多动使精神混乱；戒多话，多话损伤精神；戒多忧，多忧使精神郁结；戒多思，思虑多刺激精神；戒久睡，久睡使精神疲倦；戒久读，久读使精神苦劳。
