Look before you leap. 三思而后行.
Seeing is believing. 眼见为实.
Strike while the iron is hot .趁热打铁.
Never dater till tomorrow that which you can do today.今日事今日毕.
He laughs best who laughs last.谁笑在最后,谁笑得最好.
Even Homer sometimes nods.智者千虑,必有一失.
Every lover see a thousand graces in the beloved object.情人眼里出西施.
Eyes are bigger than ones stomach. 心有余而力不足.
