A man cannot whistle and drink at the same time.
一心不能二用.
A work ill done must be twice done.
未做好的事情,需要重新再做!
Better late than never.
遲做總比不做好.
Between two stools one falls to the ground.
腳踏兩頭要落空.
By the street of "Bye and bye" one arrives at the house of "Never".
遷延因循,一事無成.
He that doth most at once doth least.
想一次做完所有事,結果一件也做不完.
Draw not your bow till your arrow is fixed.
事未齊備,切莫妄動.
Do business, but be not a slave to it.
要做事,但不要做事情的奴隸.
