毕恭毕敬 cap in hand：He always treats his boss cap in hand.
得意忘形 to leap out of one's skin
捷足先登 The early bird catches the worm.
欲速则不达 Haste makes waste./More haste, less speed.
欲加之罪，何患无辞 Give a dog a bad/an ill name and hang him.
混水摸鱼 to fish in troubled waters
贪小失大 penny-wise and poundfoolish
习惯成自然 once a use forever a custom
挂羊头卖狗肉 cry up wine and sell vinegar
小Car笔记：
troubled waters：混乱状态，波涛汹涌的水
poundfoolish：省小钱吃大亏的，因小失大的
cry up：夸奖(称颂)
