If you would have a thing well done, do it yourself.想把事情来做好，就得亲自动手搞。

 

He that doth most at once doth least.什么都想一次做完，结果一件也做不完;贪多嚼不烂。

 

It is lost labour to sow where there is no soil.没有土壤，播种也是徒劳。

 

It is right to put everything in its proper use.凡事都应用得其所。

 

Affairs that are done by due degrees are soon ended.按部就班，事情很快就做完。
