A midd is as good as a mile.
Actions speak louder than words.
Knowleage is power.
An idle youth,a needy age.
Berrer late than never.
Better pills may have wholesome effects.
Do wrong once and you'll never hear the end of it.
Faint heart never wins fair lady.
Look before you leap.
To pay a person is his own coin.

A miss is as good as a mile. 失之毫厘，差之千里
Actions speak louder than words. 事实胜于雄辩
Knowleage is power. 知识就是力量
An idle youth,a needy age. 少壮不努力，老大徒伤悲。
Better late than never. 亡羊补牢，犹未为晚。
Better pills may have wholesome effects. 良药苦口
Do wrong once and you'll never hear the end of it. 一失足成千古恨
Faint heart never wins fair lady. 不入虎穴，焉得虎子/懦夫难赢美人心
Look before you leap. 三思而后行
To pay a person is his own coin.以其人之道，还治其人之身
