Never say die.永不言敗。
New wine in old bottles.舊瓶裝新酒。
No man is content.人心不足蛇吞象。
No living man all things can.世上沒有萬事通。
No cross， no crown.不經歷風雨，怎么見彩虹。
No garden without its weeds.沒有不長草的園子。
No man can do two things at once.一心不可二用。
No man is born wise or learned.沒有生而知之者。
No man is wise at all times.聰明一世，糊塗一時。
None are so blind as those who won't see.視而不見。
None are so deaf as those who won't hear.充耳不聞。
All good things come to an end。一切美好的事物皆有終結之時。
Never too old to learn， never too late to turn.亡羊補牢，為時未晚。
