Kill two birds with one stone.一箭双雕。
Every bean has its black.金无足赤,人无完人。
He that promises too much means nothing.轻诺者寡信。
He who would hang his dog gives out first that it is mad.欲加之罪,何患无词。
He that rune fastest gets the ring.捷足先登。
Riches have wings.富贵无常。
Diamonds cut diamonds.棋逢对手,将遇良才。
The best of friends must part.天下没有不散的宴席。
No fire without smoke.无风不起浪。
it is the first step that is troublesome.万事开头难。
Go to the sea,if you would fish well.不入虎穴,焉得虎子。
Fact is stranger than fiction.大千世界,无奇不有。
A crow is never the whiter for washing herself often.江山易改,本性难移。
A friend is best found in adversity.患难见真情。
You are never too old to learn.活到老,学到老。
Unpleasant advice is a good medicine.忠言逆耳利于行。
Time tries all things.时间检验一切。
Practice is better than precept.身教重于言教。
Doing everything is doing nothing.贪多嚼不烂。
Faith moves mountains.精诚所至,金石为开。
Keeping is harder than winning.创业不易,守业更难。
Good (or Great) wits jump.英雄所见略同。
Custom makes all things easy.习惯成自然。
One can not be in two places at once.一心不可二用。
No weal without woe.福兮祸所伏,祸兮福所倚。
