Failure is the mother of success.失败是成攻之母
Practice makes perfect.熟能生巧
All roads lead to Roma.条条大道通罗马
Don't judge a person by the clothes he wears.不能以貌取人
Don't count your chickens before they are hatched.切莫过于乐观
Learn to walk before you run.循序渐进
It's easy to be wise after the event.事后诸葛亮
As you make your bed, so you must lie in it.自食其果
All that glitters is not gold.闪光的东西并非都是金子
Many hands make light work.人多力量大
