no pains no gains.没有付出就没有收获.
once bite,twice shame.一遭被蛇咬,十年怕井绳
more haste less speed.欲速则不达
an apple in one's eye /beauty is in the beholder’s eye.情人眼里出西施
don't teach the fish to swim 关公面前耍大刀
once for all 一劳永逸
one man's meat is another man's poison 萝卜白菜各有所爱
a dog in the manger 站着茅坑不拉屎
the early bird catches the worm 早起的鸟儿有虫吃
