It's no use crying over spilt milk/What's done cannot be undone
覆水难收
The grass is greener on the other side of the fence
隔岸风景好;邻家芳草绿。
Hunger is the best sauce
饥饿是最好的调味品
Better late than never
迟做总比不做好。
God helps those who help themselves
天助自助者。
Love me,love my dog
爱屋及乌
He bites off more than he can chew
贪多嚼不烂
To teach a fish how to swim
孔子面前卖文章。
Rome wasn't built in a day
伟业非一业建成。
Well begun,half done
好的开始是成功的一半
Every cloud has a silver lining
否极泰来
